I'll make you famous

Symmetry on X, Y, and Z would be much appreciated. It would be killer if there was radial symmetry, with an editable number, that would speed up workflow immensely.

Definable grids, and grid snapping for top view, side views, bottom view. That would greatly help while aligning meshes.

Object widgets, for move, scale, and rotate.
Customizable hot-keys for everything.

Snap for primitive hot-spots. Center, center-top, center-bot. Definable radial snap. [example]If set to 15 degrees, would snap to each 15 degree loc, based from center-point of prim.

free-form primitives. For example, if you wanted to edit the cap depth of a HyperRod, instead of using a key to switch to that function, you mouse-over the cap of the HyperRod, the cap highlights, and then you can click-drag the height of the cap.

Sorry, forgot one. Speed modeling is one of the best features available. Groboto allows the user to rapidly prototype, and publish ideas. While building, the user spends quite a bit of time moving the model around, studying it, rotating it, zooming in and out.. etc. Because of this, I suggest:
::Right-Click and Drag, to Rotate the model
::Left-Click to Pan, and Select Objects
::Scroll-Wheel to Zoom In and Out.
::Cntrl-Click for Pop-Up Menu

Also, the option to be able to alt-click-drag and draw a selected primitive, at snapped loc.

Btw, right now Scroll-Wheel zooms in and out, only you need to hold Control to do it. We felt this was necessary because it's easy to bump the Scroll-Wheel inadvertently and lose a carefully set up view. In any case, this should simply be a user preference - whether holding Control is needed to enable Scroll-Wheel.

Another thing - holding Control is consistent with the other currently available camera shortcut - Control-LMB drag for orbiting.
