Ahhh - thank you, got it - they changed it with CC - you used to be able to set the % in the top area, and check what dimensions that gave you in the lower.
Now, you can change dimensions (mm, inches, cm) to % (which I didn't realize) but... you'll have no indication of what size choosing e.g. 150% will give you.
Was better before, a regressive change imho, but... at least it's there.
