One feature that would be nice to have would be to let Recipe's use an OR type condition for the input. I should be able to specify that to make a bomb you need casing + (tnt OR gunpowder). Otherwise, we end up cluttering up the recipes with too many similar recipes.

Had the same thought earlier. Was debating adding a basic "Explosive Compound" ingredient that they can all use instead. Think some sort of common resourse library might be needed sooner rather than later.

Plus, ammo any gun can use is dictated by a Form list. Picture 10 dif mods changing the same Form List each to add a new ammo type...
