Oh I could sprinkle the issue tracker with about 2 or 3 UX situations that I still find maddening, like how clicking to place a cursor on entry fields in the inspector is too damn picky. Often, I am inserting a minus sign or changing one digit and godot editor is very fussy compared to other IDEs.
In 4 the are going to make the side panels window-able, but still when transitioning from and to debugging the editor constantly chooses which tab is presented, like switching from console to debugger or switching away from the profiler or monitor. It's a drag on workflow.
