Want to change the brightness of your Apple Studio Display from the Gnome quick settings? look no further!
This is a simple (and I mean REAL simple) gnome slider that piggybacks off asdbctl (https://github.com/juliuszint/asdbctl) which needs to be installed in your path somewhere. Note this needs the version of asdbctl that doesn't require sudo. This extension is very lazy it fits my need but will probably cause vomiting in any reasonable developer if you look at the code (sorry!).
