The booleans do constitute a big chapter inside Wings and they deserve a careful focusing on the possibilities they offer so that they may be developed even further, wherever is possible.
Shortly, it is good news that you are revisiting them. : - )
Actually ... I made them a lot stronger in a way that is not so apparent to users yet.
Instead of exporting each "tidbit" or part as a separate file (expensive) ... I can now export them all
in a single OBJ (wavefront file) and specify the Boolean operations using indexes into that file. So I send to CarveCSG a "receipe" and also a master file of all the parts. It will have nice benefits in some situations.
