That could be it as I don’t understand those bunch of characters on the status state value, but if I copy the whole konsolerc file and on a fresh install paste it back the toolbars keep visible even if I had set them to be hidden before backing the file up.
Not for me. I don’t have a fresh install here right now, but if I move konsolerc and start Konsole, it comes up with the toolbars along with other default settings, if I move it back, the toolbars are gone again.
