Auto Scroll for YouTube Shorts + Extra Features – Version 4.4 (by Justn)
What it does (100 % mouse-only, no keyboard required):

•Auto-advances every YouTube Short when it finishes or loops — unless you move the mouse.
•Hold right-click or left-click → move the mouse as much as you want without breaking auto-scroll (perfect for liking, or reading the screen). Release right-click or left-click and a tiny hand twitch won’t count — only deliberate movement (≈100 pixels) disables auto-scroll for the current loop.
•Click the Dislike button → instantly skips to the next Short (no waiting for the end).
•Any Short with SponsorBlock segments (sponsor, intro, outro, self-promo, etc.) → automatically skipped the moment it loads. This is unfortunate but pretty rare generally speaking. But Sponsorblock caused significant problems and required extensive code writing to account for it. The easiest solution was to skip all video shorts with SponsorBlock segments.
•Works only on /shorts/ pages — completely inactive on normal YouTube videos.

Visual toggle button (bottom-right corner):

•Red pill with “AUTO” in white → auto-scroll is active and will advance this Short.
•Red pill with “MANUAL” in bold black + white glow → you moved the mouse → auto-scroll is paused for this loop only (next Short goes back to AUTO automatically).
•Gray pill with “OFF” in white → script is disabled (click the button to turn it back on).

Install once and enjoy the smoothest, most intuitive Shorts experience possible.
Perfect for power users who want total control with nothing but the mouse.

Note: SPA issue in YouTube has been duly noted. Sometimes you need to refresh the page for the auto scroll pill at the bottom right to appear. And if you hit "back" on the browser to a non youtube shorts page, the pill may remain. A simple refresh will eliminate this problem. I could have solved the problem with the SPA by expanding the @match to include all youtube pages, and then create tighter controls to ensure the pill doesn't activate on anything but YouTube shorts pages, but it created quite a few ripple effects that made solving those problems far more complicated and this goes against my code philosophy: simple is always better.
