In case you weren’t aware—though I bet many hardcore GNOME users already have it installed—there’s a GNOME Shell extension called “Just Perfection” that replaces many single-purpose extensions for your GNOME desktop environment, and the latest release works with GNOME 40.
The “Just Perfection extension” does a lot of things to let you make the GNOME desktop your own. For example, in GNOME 40 it lets you hide the dash in case you want to use a third-party dock-like application, or you can just move the top panel to the bottom instead, or disable the panel completely!
