Well, initially I didn't understand what exactly @Charon wants, I thought he wants something like a map key/legend , that's why I made this too(with tabs):
So @Charon wants manufacture description and @drages wants more weapons categories.
Of course I will go first if you want to add the code for it and if you don't like this changes to be in xce, maybe we can do something so it only take effect under certain conditions.
