I’d like to know if it’s possible to set margin/padding for all sides via click instead of dragging the mouse?
You can drag the values for all sides via shift-key and opposing sides via alt-key.
Why can’t we hold shift/alt and click on any region and set all sides via entering a value in the popup? I’m a fan of accuracy and would much prefer simply entering my desired value!
I checked the shortcuts and tested any combination. Holding shift and clicking a side opens the popup but after entering it only sets the clicked region to the value.
I’m not sure adding this to the wishlist, but maybe someone reads this and asks the right person 
I don’t want to know how much time I’ve spend manually entering each region plus typing the viewport unit.
Thank’s for reading!
