I would like to see up/down arrows. It would make adjustments easier to control for finer adjustments.
Also always keep in mind something that some people are not aware of is that you can type in your own number on the resizing scale rather than just moving the ball.. It is a fine way of tuning for now.
That's true but it can also be problematic. If you type in a number and you decide that that number is too great or too small, you cant just adjust that number up or down, you have to type in a whole number. Not good for fine adjustments either.
