Currently, I am working on some 3-D stuff to add to MXM. As I am doing support for 3-D in the intro screen, it's not much more for me to add it to the skinning and ActionScripting.
The support will also allow you to access .X and .XBG models (hopefully) in the file browser.
There are still a few critical things to wrap up. Between work and MXM, I've been a bit drained lately, but working on the 3-D stuff has "infused me" with a bit higher spirits and enthusiasm.
HOWEVER - if you feel you can do a better, quicker job than I, by all means start work immediately. The code for 0.9n.6 is out there, so all you need to do is start working on it. Nobody else has offered to "take the mantle" so your offer would certainly be unique and noteworthy.
In the meantime, I will continue working on things and try and get the next release out as soon as humanly possible (I am, after all, only one person, one with real responsibilities, real family, and real work). Please do forgive me, however, if I indulge in a couple of hours of playing games once or twice a week, or the occasional movie; or even if I do not code a single line when I come home after standing for ten hours hunched over a test bench at work trying to debug code sent from halfway around the world, then spend two hours on the phone explaining things to the Japanese team that has to fix it.
