How it works

Chromium, Electron and CEF all have autoscroll built in. On Linux it is off, because middle click pastes there. One flag turns it back on:

--enable-blink-features=MiddleClickAutoscroll

Adding it to every app by hand is a pain, and updates can undo it. This tool does it for you:

• It finds every app built on Chromium. AppImages too, without unpacking or starting them.
• It puts the flag where the app reads it: the app's flags file, or a copy of its menu entry in your home folder.
• It watches for new apps and covers them on their own.
• It only writes to your home folder, and disable puts everything back.

Browsers get a spelling of the flag that shows no warning bar. Brave and Helium also get their own name for the feature. A browser ignores names it does not know.

Steam builds its own command line and repairs any file that looks changed. So the flag goes into the script that starts its web helper, and the file keeps the size and date Steam expects. Steam finds nothing to repair, and autoscroll works in the store and the library. After a Steam update, the patch comes back on its own.
