Hi. I would like to suggest, that when you click on anythign in the BOX section "Space-Z" that the cursor would be automaticcaly set in the field, where you put values, so when you start typing, it would type the number/var. what happened to me = I clicked on padding and wanted to type 20 (as I was expecting it, to type the number automatically in the value field). But instead of that, the breakpoints switched to "2 - 1120 & below" - which I didn't noticed right away and kept styling the whole thing in "2" rather then "1 - all screens". This way you save one click and are able to type the number/var imediatelly.
