I think I'm not too far away from having the regular non-3D part of the UI done (like buttons and side pane, etc...) so that will be one major piece but then there will be a lot of work left for geometry and 3D display things. I won't really know how long each area will take until I have spent some time with it.

The end result of all this rewriting work should be a 64-bit version with a native Mac compile which should be a better base to build off of for some time to come.
