One thing I am confused about though with quick rotate, using painting example, your walls wont always be along world grid, so rotating 45 might never line up with your wall, are you sure you dont want some rotate relative to your current camera facing? tracing into world to find surface normal and rotate relative to that, in increments, could also work.
Keep in mind mind we have opportunity to design a new editor here so we might as well think about it before proceeding.
Any thoughts?
Now its just about finding the right key to use in the editor, with my Vertex Snap plugin
