I think it makes sense to additionally use GM_registerMenuCommand (if GM_registerMenuCommand exists in the userscript extension's context (typeof GM_registerMenuCommand === "function")) to make opening of the settings a bit more obvious and easier. Just a minor improvement.

Anyway thanks for the working UJS.

Also add any signal (like the button blinking, color changing, or something else) that a file is successfully saved to the disk.

Currently it just has progress bar of downloading, but it saves the result file to the disk only after some seconds.
