This currently does not support gnome 44 and I tried to make it work by adding gnome44 to supported versions manually, the quick toggle then loads but shows up broken with no text inside the button.
This is a nice extension, but what would make it really great - is a setting for one-shot auto brightness, that is turn on auto brightness for a second on screen powering on, and then turn it off. Such setting is present on some android smartphones, and it's really useful for people who used to control brightness manually, but frequently puts their devices to sleep in one place and turns it on in another.
