None of the layout presets corresponds to / restores the default layout
None of the layout presets here:
corresponds to / restores the default layout. That means that once you've clicked one of those five buttons, it is impossible to restore the default layout. That's quite a big gotcha.
I also tried to delete all files and folders listed here https://community.kde.org/Kdenlive/Configuration, but it did not reset my layout back to the default. I did not have the folder %LocalAppData%\kxmlgui5\kdenlive\kdenliveui.rc
though so I was unable to delete that one file. Could that Wiki post be outdated?
Version 20.12.1
For reference, here is what the default layout looks like https://invent.kde.org/multimedia/kdenlive/uploads/780e84af6b53be8042fec1711b58670b/image.png (ignore the red scribbles).
