Please do. I'm hoping to have npc and weapon scripts in and working by December. I need to port over a few things from DD's master branch that I did, and get the enemy flags and weapon editors in both the Enemy Editor, and the Item Editor. The flags are going to be like Item Editor misc flags--sixteen of them, to control certain enemy aspects.
The primary use is for moving QR-based enemy behaviour over to the editors. Items are close to done, in that regard, so enemies are next.
There is a roster of various 2.50.x bugs that I'm sorting through at present; trying to get 2.53 into Gamma and be done with it before the year's end.
