Which directories should I delete so that the next launch of the IDE is a "fresh" start?
I have identified these directories on Linux:
~/.arduino15
~/.arduinoIDE
~/.config/arduino-ide
~/.config/'Arduino IDE'
Background:
I managed to accidentally drag the debug icon from the sidebar and did not manage to get it back. I deleted the mentioned directories in the hope that it would be the equivalent of starting the IDE for the first time, but that was not the case.
Kind regards!
