Sorry, I've never used it before and didn't realize it was this simple. I've just read the manual and see that everything's working.

Doesn't work on Manjaro. It didn't launch at all, after installing gtk2 it does, but  looks completely broken. I can't do anything except create collections and items.

Sometimes when I make a mistake, it gets stuck. I can't delete anything and cant type further. What can I do?
