To adjust width of the projects panel, I use the mouse to drag its right-hand side-bar.
The screen area that is eligible for ‘grabbing’ is so thin, that the mouse cursor tends to move over it.
Soemtimes it just keeps skipping over the area. I move the mouse (slowly…) cursor changes to double arrow, and poof - I’ve gone too far.
Slowly move back - same story.
Eventually, with patience, I usually win. (ha, but it’s not an action game)
Would it be possible to broaden the grabbable area by a few pixels?
