May I suggest adding the ability to upload a custom bump-map texture for an object? Bump-map textures would have to fall within a pre-set limit (depending on the render engine), and would be grayscale (or channel-selectable would be better! RGB bump-mapping with scriptable setting for which channel to bump-map!!).
This would allow the savings of prims for designing things with 'buttons' on them. My next Feature Suggestion (Touch X,Y coordinates) will make crystal clear how this benefit would be complete.
Edit: A simpler/better suggestion is here:

This would be a better choice than what I suggested
