Actually, yes. There is a plan to add support for OS X. Currently I have no specific deadline for the next release, nor I can't promise that OS X support...

It definitely can be done, though not so easy as with maps. I'll have to replicate what original ZDoom code does with skill definitions, including reading them in correct order...

Yep, can be done. Will be added in the next version.

I have had similar thoughts about built-in "favorites" or "profile" browser. Will be in some future version.
