The description listed the technologies it happens to cover, which reads
like a compatibility list and dates the moment something new turns up. What
it actually does is enable autoscroll wherever that is possible.
Middle-click autoscroll for every Chromium-based application on the system -
Electron and CEF applications, Chromium-based browsers, Flatpaks, Spotify and
Steam - plus anything installed later. Built from source out of the upstream
release tarball, like cachy-auto-update.
