When we go to Konsole main menu » Settings » Toolbars Shown and check or uncheck any option, where does it get stored?
I checked ~/.config/konsolerc and it was not stored there.
I actually toggled them and checked all files in my system that were changed at the same time I toggled them and I still could not find.
My ~/.local/share/kxmlgui5/konsole/ has no files in it, both on Arch and Void Linux. I also tried creating a partui.rc file as well as konsoleui.rc to see if it would get populated when changing which toolbars are shown and which aren’t but it did not work. My KDE Version is 5.27.10 on both distros.
Nice!
