Please no βvalue draggersβ.
These are horrible to use, you always need too much sensitivity to hit the right value. In usability tests this control element fails regularly.
Instead, please use more select boxes (with direct input of the value), as already implemented for the font size.
So also for the borders, the line spacing, the paddings and all other numerical values.
The only exception is the character spacing.
These select boxes are much easier to use and allow a quick selection of the values.
I could imagine values like 1,2,3,4,5,10,20,20,40,50 for the paddings.
