<h2><strong>I. ABOUT THIS SCRIPT</strong></h2>
<p>This script works “out-of-the-box” on local directories. To enable it to work on a remote directory, add its url to the list of included/allowed sites in your userscript manager’s settings for this script.</p>
<p class="bold"><a href="https://openuserjs.org/scripts/gaspar_schot/Supercharged_Local_Directory_File_Browser" class="has_icon_before link text_color_default" target="_blank">Script home: openuserjs.org</a></p>
<p><span style="float:left; margin:4px 6px 0 0;">${ SVG_UI_Icons.ui_layout }</span>The UI consists of two main parts: the navigation <strong>Sidebar</strong> on the left and the preview <strong>Content Pane</strong> on the right. The Sidebar shows all the files in the current directory, while the Content Pane shows a preview of the items selected in the Sidebar.</p>
<p>The <strong>Sidebar</strong> contains a <strong>Header</strong> area, the <strong>Directory List</strong> itself, and a <strong>Footer</strong>.</p>
<p>The <strong>Sidebar</strong> is resizeable, or it can be hidden entirely via the double-chevron button at the Sidebar top right.</p>
<p>The <strong>Sidebar Header</strong> includes a <strong>Parent Directory</strong> button, a <strong>Parent Directories</strong> menu, and the <strong>Main Menu</strong>. and below these, <strong>Show Details</strong> and <strong>Show Invisibles</strong> items, a <strong>Show Grid</strong> button (when appropriate), and sort by <strong>Name</strong> or <strong>Default</strong> items; if <strong>Show Details</strong> is selected, additional sorting options are shown, along with the <strong>Text Editor</strong> item. All of these items are also available in the Main Menu, and some can be toggled via a keyboard shortcut (see below).</p>
<p> The <strong>Content Pane</strong> displays the selected sidebar item.</p>
<ul><li class="no_hover no_highlight">The content pane can be focused by tabbing from the sidebar or clicking.</li>
<li class="no_hover no_highlight">Clicking the title of the content pane title reveals a playlist item than can be copied into an m3u file.</li>
<li class="no_hover no_highlight">Previewed Content</li>
<ul><li class="no_hover no_highlight">Directories
<dl><dd><Previewed directories in the Content Pane inherit the sorting and other UI preferences from the Sidebar directory list. They can be navigated independently from the Sidebar via the “Parent Directory” link in the header or Cmd-Up Arrow.</dd>
<dd>An item in the content pane header allows previewed directories to be opened into the sidebar.</dd>
<dd>A selected item can be previewed by pressing the spacebar. This is similar to the “quicklook” function in MacOS.</dd>
<dd>Double-clicking a selected directory list item or typing Cmd-Down Arrow will open it in the content pane, replacing the previewed directory. Closing the item via the Close Button or Cmd-W will restore the original previewed directory.</dd>
</dl>
</li>
</li>

<dl class="border_top_x padding_top_1rem"><dt>1. Go to Item...</dt> <dd>Select a sidebar item by its row number (displayed if "Show Numbers" pref is set). Useful especially for large directories. Directory list can also be navigated by typed strings.</dd></dl>
<dl class="border_top_x padding_top_1rem padding_bottom_1rem"><dt>2. Sort By...</dt><dd>Sort directory items by <strong>Name</strong>, <strong>Size</strong>, <strong>Date</strong>, <strong>Kind</strong>, <strong>Extension</strong>, <strong>Duration</strong> (media items only). <strong>Default</strong> sort = sort items by Name, with directories on top.</dd>
<dd>Clicking the sort preference again will reverse the sort.</dd>
<dd>Sorting preferences are also available in the Sidebar Header.</dd>
<dd>Note that many server configurations don't report directory size, so when sorting by size, directories will be on top, sorted by name.</dd>
</dl>
<p class="border_top_x"><strong>3. UI PREFERENCES</strong><br />Selecting one of the sorting or preferences items will add the new preference setting to the URL query string, so that the setting will persist as you navigate within the same window, or if you bookmark the page.</p>
<dl><dt>a. Light Theme/Dark Theme</dt> <dd>Change the UI theme.</dd></dl>
<dl><dt>b. Alternate Backgrounds</dt> <dd>Alternate background colors for directory list items.</dd></dl>
<dl><dt>c. Show Numbers</dt> <dd>Show numbers for directory list items.</dd></dl>
<dl><dt>d. Use Custom Icons</dt> <dd>If enabled, use file and directory items provided by the script; if disabled, use the browser's default icons.</dd></dl>
<dl><dt>e. Show Image Thumbnails</dt> <dd>Replaces the generic image file icon with a small thumbnail of the image itself. Enabling this setting may slow down page load, because each image file in the directory must be processed.</dd></dl>
<dl><dt>f. Use Large Image Thumbnails</dt> <dd>If "Show Image Thumbnails" is enabled, the thumbnail enlarged.</dd></dl>
<dl><dt>g. Always Show Image Thumbnails</dt> <dd>Image thumbnails are always shown, no matter how many images are in the directory. This overrides the default behavior which automatically disables thumbnail display for directories containing more than 2000 items in order to improve performance.</dd></dl>
<dl><dt>h. Set UI Font</dt> <dd>Set a custom font for the UI.</dd></dl>
<dl><dt>i. Scale UI</dt> <dd>Scale the entire UI (50%–150%). Double-click the label to quickly reset the scale to 100%.</dd></dl>
<p class="border_top_x"><strong>4. FILE HANDLING PREFERENCES</strong></p>
<dl><dt>a. Show/Hide Invisible Items</dt> <dd>It does what it says on the tin...</dd></dl>
<dl><dt>b. Show/Hide Ignored Items</dt> <dd>Ignored items include files that the browser cannot handle natively (e.g., common Office and graphics files, various binary files, etc.). Hide them to reduce clutter.</dd>
<dl><dt>c. Ignore Ignored Items</dt> <dd>Prevent normal browser behavior for handling such files, which is to open a download file dialog.</dd></dl>
<dl><dt>d. Autoload Index Files</dt> <dd>Automatically load "index.html" or similar files in the Content Pane when the directory loads.</dd></dl>
<p class="border_top_x"><strong>5. MEDIA PREFERENCES</strong></p>
<dl><dt>a. Autoload Media</dt> <dd>If enabled, automatically load the first media file (audio or video) when the directory loads.</dd>
<dd>For audio files, this will also automatically load any “cover art” (image file) found in the same directory. The script will first look for an image file with <i>exactly</i> the same name as the currently selected/playing audio file, followed in order by files containing the words “cover”, “front”, “album”, “jacket”, “sleeve”, “cd”, “disc”, “insert”, “liner”, or “notes.” If it finds no matching files, it will load the first image file it finds. Cover art will be automatically loaded whenever a new audio file is selected for playback.</dd></dl>
<dl><dt>b. Autoplay Media</dt> <dd>If enabled, play the next media file when the currently playing media file ends.</dd></dl>
<dl><dt>c. Play All Media Files</dt> <dd>If disabled (and Autoplay Media enabled), only play media of the same type (audio or video) as the currently playing media file.</dd></dl>
<dl><dt>d. Loop Media Playback</dt> <dd>Loop media playback to the first media item when the last media item ends and continue playing. This option can also be enabled from the audio player.</dd></dl>
<dl><dt>e. Shuffle Media Playback</dt> <dd>Randomize the order of media playback. This option can also be enabled from the audio player.</dd></dl>
<p class="border_top_x"><strong>6. TEXT EDITING PREFERENCES</strong></p>
<dl><dt>a. Text Editing Enabled/Disabled</dt><dd>If text editing is disabled, text files are displayed as normal files.</dd></dl>
<dl><dt>b. Text Editing Options</dt><dd>Toggle the Text Editor. Select Editor UI theme: Default = same as main UI. Toggle split view. Select view of raw text, preview text, rendered HTML.</dd></dl>
<dl class="border_top_x padding_top_1rem padding_bottom_1rem"><dt>7. DEFAULT PREFERENCES</dt><dd>Resets UI to defaults by removing manually set preferences from the URL query string.</dd></dl>
<p class="border_top_x"><strong>8. PLAYLISTS</strong></p>
<dl><dt>a. Open Playlist/Filelist</dt> <dd>Click to load a local .m3u file. See below for more details.</dd></dl>
<dl><dt>b. Make Playlist/Filelist</dt><dd>Save the files in the current sidebar directory as an .m3u playlist/filelist. Choose audio, video, all media, all non-media, all items, directories or files only.</dd></dl>
<dl class="border_top_x padding_top_1rem"><dt><strong>9. OPEN FONT FILE</strong></dt> <dd>Load a local font file to view information about the font and its complete glyph repertoire.</dd>
<dd>Glyph grids can be navigated with the arrow keys. Individual glyphs can be selected by clicking them or pressing <kbd>Return</kbd>.</dd><dd>Individual glyphs may be saved as .svg files.</dd></dl>

<h2 id="other_functions" class="border_top_x padding_top_1rem"><strong>IV. OTHER SCRIPT FUNCTIONS</strong></h2>
<dl><dt>NAVIGATION</dt>
<dd>Use the up and down arrow keys to navigate items in the sidebar and previewed directories in the content pane.</dd>
<dd>Use the left and right arrow keys to navigate items of the same kind as the currently selected item.</dd>
<dd>Use the Tab key to toggle the focus between the sidebar and the content pane.</dd>
<dd>Type a letter or letters to navigate the directory by file name.</dd>
<dd>Type Cmd+Down-Arrow to navigate to the selected directory.</dd>
<dd>Click a directory icon in the sidebar or select it and type Cmd/Ctrl Right Arrow to open subdirectory; click again to close or type Cmd/Ctrl Left Arrow.</dd></dl><dl><dt>Images, Fonts, Font Glyphs</dt><dd>Previewed items can be scaled with <kbd>Cmd/Ctr +/–</kbd> keys.</dd></dl> <dl><dt>IMAGE AND FONT GRIDS</dt><dd>If a directory contains images and/or font files, the "Show Grid" icon will appear in the sidebar. Click it (or type <kbd>Cmd/Ctr+G</kbd>) to show a grid of the available items.</dd><dd>Grids can be navigated with the arrow keys, and individual grid items may be viewed by clicking them or pressing <kbd>Return</kbd>.</dd><dd>When a grid item is being viewed, the grid can still be navigated with the arrow keys.</dd><dd>Closing a selected grid item will show the grid again.</dd></dl>
<dl><dt>PLAYLISTS AND FILELISTS (m3u)</dt><dd>The script supports basic .m3u playlists containing links to audio or video files. It also has custom support for "filelists," which are standard .m3u files that contain links to <i>any</i> type of file or directory.</dd><dd>Note: if you change the extension of an ordinary .m3u file to .txt, the script will read it normally as an editable text file.<br />Double-clicking the selected file in the sidebar, or typing <code>Cmd/Ctr + Down Arrow</code> or <code>Cmd/Ctr + Return</code>, will open the playlist/filelist in the sidebar.<br />NOTE: The text must begin with #EXTM3U for this work.</dd></dl>
<dl><dt>CUE SHEETS (cue)</dt><dd>When a media file (audio or video) is loaded, the script will look for a .cue file in the same directory with <i>EXACTLY</i> the same name as the media file.</dd><dd>If it finds one, it will load the Track ID, the PERFORMER, the TITLE, and the INDEX (time position) into a menu next to the audio player; there is no support for other commands.</dd><dd>Tracks can be selected by clicking the item, and played or paused by clicking the selected item.</dd><dd>.cue files can also be selected independently in the sidebar and edited and saved (locally). This may be handy for creating "on the fly" bookmarks for a long media track before closing the page.</dd><dd>Note that you can also create and save (locally) a new .cue file by using the Text Editor.</dd><dd>Note (MacOS): If you prefer not to clutter the sidebar with .cue files, you may make them invisible by adding a dot to beginning of the file name; the script will still find them.</dd></dl>
<h2 id="troubleshooting" class="border_top_x padding_top_1rem"><strong>V. TROUBLESHOOTING</strong></h2>
<dl><dt>The script doesn‘t work with a specific directory.</dt><dd>If you have a javascript blocker installed in your browser (and if you don’t, you should), try disabling some of the site-specific scripts and XHR requests, as they may be interfering with the execution of this script.</dd><dd>Alternately, if you do have a javascript blocker installed, you may need to allow some scripts and XHR requests instead.</dd><dd>If the open directory still does not display correctly, check to see if cookies from the site are blocked.</dd><dd>Try deleting preferences from the Main Menu or removing the query string from the URL in the browser.</dd></dl>
<dl><dt>A specific item in a directory does not display correctly.</dt><dd>Confirm that the file is one that browser is capable of rendering. This script cannot display files that the browser itself cannot display.</dd><dd>If the item is from a playlist (m3u) and links to a remote site (e.g., archive.org), check your javascript blocker and cookies for any that need to be allowed from that site.</dd></dl>
