I changed a few random numbers around in the 3D BoA editor code, and somehow ended up with a bigger screen area.

It's based on a very out of date version of the editor, but in case you want to use it, you can get it here (mac only).

(all I did was download the code off Niemand's svn and change a few numbers here and there - an example of the screen size can be found here)

This is now redundant as the mac editor now supports resizable windows. You can get the proper editor HERE.
