I’ve noticed the margins get larger when switching to the ‘full window’ mode. It is most noticeable on the left of the window, although the margins on the right do expand a little as well.
I really like this more minimal view, but it always means I need to make my window bigger, which defeats some of the benefits of the minimal window dressing! Would it be possible to keep the left and right margins the same as in the normal mode?
Otherwise, really enjoying the current Mac version of Bike - very polished!
