I remember one time I installed a lot of themes for my session and I broke something and the themes changed my icon files forever and I had to reinstall Ubuntu!!
Should I just stick to changing my wallpaper and other small tweaks? I don’t really like using vanilla Ubuntu anymore, it doesn’t feel like me. Thank you very much!!
I disagree eight the other poster. Please use whatever distribution you feel most comfortable with!
With KDE Plasma you might want to wait for the upcoming 6 release, since they simplified a lot of stuff (and also Wayland per default iirc?). Kubuntu will take longer than Feodora to ship though.
I personally used Plasma a lot, and I understand the being overwhelmed. What I did was just working with it, and figuring stuff out along the way. I think KDE Plasma is awesome, especially for customization!
