What I want to do:
Hide the GNOME Panel while Overview/App Grid is open, but show it on the desktop. So when I go to my activities overview or look at my apps, the panel is not there. But when I am looking at the desktop, it is there, and I can interact with it and everything.
What I've Tried:
I've tried variations of Hide Top Bar extensions without any luck.
Theoretically
You should be able to make an extension to do this, right? I have very very little knowledge of how to make an extension for GNOME, so any help would be appreciated.
