I wish Santa would bring me ArchiCAD 9 with one simple option included: "Don't display trailing zeros"! 🙂
It's driving me nuts when I need to have all the dimensions in cm and want to have 1 mm precision, but most of the dimensions are ,0 and only a few really need the decimal number. This option is available in AutoCAD so I don't see why it can't be embedded here... It can very easily be integrated into Options > Preferences > Dimensions menu with just one more check box added.
