About ImmediateGUI
An IMGUI inspired GUI Framework for javascript thats designed to be as simple to use as IMGUI.
Its actively developed, which means stuff might change and bugs (most definitely) will occur when using this
Supports most of the default controls one could need, can drag the gui around with the mouse, toggle between light/dark mode etc.
For how to use it, check the example code down below (and look at the code of the library)
Example Images (and pseudo code how they were made)

const $$ = new ImmediateGUI({
theme: 'dark',
position: 'left',
width: 400,
draggable: true,
title: 'Example GUI',
titleLeftAligned: true,
});
$$.BeginTabs(['Tab 1', 'Tab 2', 'Tab 3'], 0);
// $$.SetActiveTab(0) is implicitly called when the first tab is created
$$.Button("Tab 1 Button 1", () => { console.log('Tab 1 Button 1 clicked'); });
$$.SetActiveTab('Tab 2'); /* Same as calling .SetActiveTab('1') as the second tab is the tab with the text 'Tab 2' */
$$.Button("Tab 2 Button 1", () => { console.log('Tab 1 Button 1 clicked'); });
$$.Textbox("Tab 2 Textbox 1", "Tab 2 Textbox 1");
$$.ToggleSwitch("Tab 2 Toggle", true);
$$.SetActiveTab(2);
$$.TextArea("Tab 3 TextArea 1");
const pb = $$.ProgressBar(0, 0, 100, true);
setInterval(() => {
const value = pb.getValue(); /* pb.value */
if (value >= pb.max) {
pb.setValue(pb.min);
//pb.value = pb.min;
} else {
pb.setValue(value + 1);
//pb.value = value + 1;
}
}, 500);
