Nope, no clipboard manager. There’s a nice extension called pano with a bunch of ridiculous dependencies that’s loaded with features. The one built into KDE is good enough for me.

GNOME looks great, but it’s just so damn frustrating to use. It’s such a weird combination of attention to detail and a focus on usability while completely missing the mark in other areas. I don’t even mind the intended workflow. That’s fine. It’s the rough edges like the hamburger menus you mentioned, extra clicks, inability to change things I expect to be able to change, etc. You have to install gnome-tweaks just to change the font.

I wouldn’t even mind the extensions either if they didn’t break during every update. Best case scenario is you have to re-enable the extension, log out and log back in. Worst case is it doesn’t work anymore and now you’re missing important functionality that the developers couldn’t be bothered to include.
