Add ability to Choose Default Unit for Width/Padding/Margin separately and Auto detect unit when value add to each field as Version 1 had. I'm used to use % to width and rems for margins/paddings. In version 1 I add % for default unit for width and Rem for paddings/Margins. So Once I type 100 to width section it automatically detect % as it's unit which saves tons of time because I don't have to type each and every time % as unit.
