I think e-on forgot to add the inteface customization options of Vue6 (did I hear a Oops?), but you can still use your V6 interface, provided you save it as "my inteface colors", "My config", or something you can easily recognize. Save your Vue6 interface, and then apply it to Vue7.
As Rutra, I never tried using the numercis tab with the alt key to nudge up or down the values. When I use the numerics tab ( and I often do) it's to enter precise values, which is, imho, what these tabs are for.
