I don't think Gnome Tweaks is an extension. Just an app that exposes some settings and DCONF options that haven't been added to the usual settings menu.
But nah, I don't use that either. Font settings really should be in the normal settings menu, though.
I pretty much change a couple of keybinds, remove a few .rpms and replace them with Flatpaks, and that's it.
This looks great, just installed it. Now to figure out how to make it looks totally transparent with just the different buttons and shrink it a bit like in the project's screenshots
I'm new to Gnome, been using XFCE and Budgie for the longest time. Does this or any other extension allow offsetting the location of the date and time? A webcam attached to my monitor mostly blocks it.
