In GC2 and some Elemental betas, the first few number keys on the main keyboard change zoom level and/or angle of view. Having some consistent, but not necessarily identical with the game, view shortcuts for the 3D editors would be nice.
I'm thinking in particular about those of us with only basic graphics skills but who want to make stamps out of several tiles. Being able to look at a set of tiles and be sure about consistent view settings would be handy. It'd also save on mouse labor in the long haul for folks doing lots of mod work.
