Dumb title but I didn't know how else to put this into words, bear with me for a sec - I am not just looking for the definition.
Years ago I tried Ubuntu which used GNOME and assumed that its desktop layout was "the default" GNOME. I later tried PopOS which also uses it and it was the same, and when eventually I installed Mint I saw that it's still fundamentally the same with some slight tweaks or different tools.
Well, few days ago I installed Bazzite (Fedora) which is also GNOME. It doesn't look anything like anything I've seen before, either in terms of mindset or technical layout. I've gone from an admittedly old-fashioned, but efficient and reliable!, layout and workflow to something that reminds me more of an apple product - its stylish, minimalist yet inefficient and utterly frustrating to get anything done with because of how opinionated it is.
When searching for common problems I often found comments saying stuff like "but try it out! it's in the spirit of gnome, it takes a while to get used to it but the philosophy is valid" and frankly I don't understand anymore what exactly gnome is and what are its design principles, if there even are any and every distro just does whatever the f it wants and call it "a gnome experience".
Looks like a new alpha for pano was released yesterday to support GNOME 47: https://github.com/oae/gnome-shell-pano/issues/315 . Otherwise you can hotfix your current build as described in the thread. I have no idea how it behaves in multi monitor setups though. On my setup it 'bumps up' your display and the clipboard entries display beneath, same like the on-screen keyboard or like a keyboard in Android. It isn't a floating window.
I'm not using any extension for the 'hot corner' functionality. It's at the top of 'multitasking' under GNOME settings for me.
Unfortunately I don't know much about manually adjusting the functionality of searching in the launcher. The extra functions I have found were just a result of experimentation, or happy accidents. I can teach it on-the-fly though. Once I've found a string which returns the function I want, but isn't the first result returned, I either click the result I want or use the arrow keys to navigate to it instead. Then the next time I use the same string, the result I wanted is returned as the first result. e.g. "sys" initially returned KDE System Settings as the first result, but I manually selected System Monitor. And now "sys" returns System Monitor as the first result.
