I can't say I've seen this anywhere, but it surprises me that no-one has apparently implemented it, nor have I heard it mentioned by anyone.
How much effort would it take to allow the loadout screen to show how many of a certain ballistic primary a ship can carry in its bank? I've been flying Unification War recently and I find it would be useful to know just how much more space a certain primary takes over another BEFORE I launch into a mission. It would also help as on some of the fighters, one bank can carry more than another.
Is this feasible? Has it already been implemented but I'm just too lazy to search for it?
