Would be neat if this could hook things like Rampant Arsenal and such to allow us to tune their ammo counts

I agree, it would be really cool. I am however a novice at programming, and don't know how to dynamically scan for modded ammo and make settings for them, which would mean that I'd have to hard-code those settings for each and every mod that I want to support. As you can probably imagine, that's a lot of work to do by hand. While I'm generally open to add support for 1 or 2 big/popular mods, I'm swamped with college at the moment so I can't really dedicate much time to it, I'm sorry.

Hey, it's been a while. Long time, really. New version for 2.0 should have some native mod support! Can you try it out with whatever mods you had in mind at the time and tell me if it works?
