I see a lot of spinners in the max interface that isn't quite wide enough to display larger numbers - especially if one is working with 3+ decimals. I propose to make the "label" or icon related to the spinner a small button that "pops out" a small box displaying input (and possibly range).

Quick fix might be to prioritize displaying numbers before the decimal separator.
PS: I'm all for compactness but not when information is lost because of it.
