Please add a 'Suppress 0 (zero) decimals in metric units' option/checkbox similar to 'Suppress 0 (zero) feet in imperial units'. This way we don't need to create 2 (similar) dimension styles: one displaying decimals, the other NOT displaying decimals. The only problem is we have to manually switch the dimension styles when moving elements and the decimals are needed to display (when not zero).
I know it is a very simple programming (IF > THEN type of thing), but i don't know how to do it.
