Though i'd kick this of to see what scripts / plugins everyone uses on a regular basis, I'll start the ball rolling with a couple i use all the time

Texture manager great script for organizing your textures will even convert to .map or other formats.

Another one i use all the time is spPaint3d
spPaint3d is a raycast based object placement tool.
Unlike geometryPaint, it doesn't use any UVs or a spacial grid to control the position of the placement of newly created objects.

So what do you use?
