1) All carried weapons should reload automatically when out of combat. As much as I love the reloading animations, you shouldn't have to manually switch between all weapon sets and stand there while they reload after every battle. Also, sometimes they don't reload no matter what you do, and then your gunner is left standing there reloading at the start of combat.
2) There should be an indication on the UI if a weapon needs to be reloaded. Like a red circular arrow or something overlaid on the weapon in the weapon sets UI frame.
Thanks!
