Denemo knows if a measure is too small to contain many notes, in fact this is hardwired to 16th notes. Its visible best with multiple staff. Add four 4th into one staff and begin with a 16th in another, the quarter will immediatly jump aside.

But in fact this should be done for smaller staffs, too. Quarter notes and especially halfs and greater take too much space.

With auto-shrinking (or make empty measures smaller and resize according to the notes in it, but 4th and bigger do not take as much space as now) Denemo could get more notation and information on one screen without scrolling without becoming not clearly arranged.
