I'd love to see some sort of history stack.

Rawvox export of solid models would be fantastic. I have no idea if it's possible, but here's the info from the developer:

Rawvox is simple raw format - every voxel is in a 3D-Grid. The data sequence:
int Magic 'RVOX'
int SizeX
int SizeY
int SizeZ
int bits_per_voxel - 8,16,32, 32 means float values
...values in array...

Having the ability to export solid models as rawvox would give us the ability to export directly to 3D Coat for painting & topology.
