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.
