Some components aren't actually explicitly listed on the summary though, in particular magazines. While the total magazine capacity appears, the individual breakdown doesn't. My missile ships inevitably end up with various mixtures of magazine types as I tweak things about. Magazines with high armour and low capacity, the converse, and occasionally even some in between get mixed together. Especially near the end of a design phase when I'm trying to make everything fit in a set tonnage, I need to alternate between adding and removing components a lot to see what can afford to be removed and what I can fit in with the saved space.
Anyway, this is probably all sounding somewhat contrived; I'll get used to it eventually and will keep quiet on this now.
