It's an annoyance when I'm doing ground missions that require an environmental suit and I have to swap out armor from inventory for myself and my away team. Not to mention, if you're running any set bonuses, you lose those when you swap out the set armor piece for the environmental one. My suggestion is to add a secondary armor slot on the captain equipment tab, just like we have for primary and secondary weapons. That way, if we go someplace that requires the environmental suit, it's essentially already equipped - all we'd need to do is activate it as normal. Additionally, this could allow us to preserve set bonuses of the primary armor (if we have them). And of course, it will save inventory slots.
