Another thing I'd like to see is some improvements to the groups editor.  It took me ages to discover that box selection selects everything in wireframe, but only selects the visible front-facing polys in the shaded modes.  Still, I have a hard time selecting small occluded polys such as inside the nostrils, especially when zooming in puts you too close to actually select them, and zooming out makes it hard to see if you really have selected the right ones.  It's especially annoying having to look up inside the nostrils to select the ones facing away from you.  It's usually easier to select the whole nose in wireframe, and then swith to shaded to un-select the polys outside of the nostrils.  (I usually give nostrils their own mat group with no specular and reduced diffuse to try and combat nose-glow) 

What the grouping tool needs is +/- selection such as in Wings.  Then selecting, for example, the nostrils' polygons would be as simple as selecting one of the polygons making up the "cap" and tapping "+" two or three times.

Might mean less "no bone" warnings, too.
