KDE for my main PC. Pretty with floating panels, KDE Connect, QT apps are often the best apps in their class and are perfectly integrated (FreeCAD, krita, okular, kdenlive, vlc, dolphin, etc…) And konsole is also very full featured.
I don’t know what KiCAD uses, but it also seems very well integrated into the KDE desktop unlike most gnome apps.
XFCE on MX Linux for an old Intel Compute Stick to keep it very usable.
~/workspace/git
That way I can also keep other stuff in the same “workspace” directory and keep everything else clean
I have a Code, simulations, ECAD, and FreeCAD folder in the workspace folder where projects or 1-offs are stored and when I want to bring them to git, I copy them over, play around in the project folders again, then copy changes over when I am ready to commit.
I could better use branching and checking out in git, but large mechanical assemblies work badly on git.
