Hey Bricks-Team,
just a small suggestion for a better UI. It would be pretty cool if you could replace the tooltip for changing the values of margin and padding since it is in the way at the moment, if one wants to change the unit back to px. You have to point the cursor somewhere below the tooltip to fade it out and then move the cursor up to select the px unit. It’s just a small thing, but it’s a pain in the a** when playing around with different units 
Maybe just move it up like in this second screenshot?
Have a great day
