the only issues I had with KDE when I was recently using it all revolved around the panel. Random crashes with “too much” interaction. Adding widgets for the panel or desktop is still to this day hit or miss. clicking the “get new widget” option is a roll of the dice if it will actually work or not or even find the thing you want. It’s still horrible at loading stuff in there. and installing whatever, again, is a roll of the dice if it will actually do it or not.
I like KDE, it’s a good and solid DE but man do they really need to focus on fixing the panels and the installation/discovery of widgets. The alternative is using the pling store and that’s just a headache on it’s own.







nix-shell is great too. sort of like a “demo” of something before actually committing to it or if you just want to use something one off without adding it to your config and rebuilding.
As a dev it’s fantastic for testing also. can just try something on a bunch of browsers without actually installing the browser. love it.
