I dont think even inventory management should require a bonus action.. it is just smth that makes gameplay more tedious, like u could just gave that potion or wep to that character before getting in combat. I dont get why people wanna sacrifice that much really..
Half of those given examples are not the way people claim, at least check 5th edition players handbook before giving a lecture about those stuff..yes u can eat during combat. Those are free actions in DnD btw not even bonus actions.
