I agree completely. I especially hate the rooms where every container is empty. On repeated play throughs I KNOW they are empty. But I still... Feel... The need... And I just open them all. Every time. Knowing they'll be empty if only because MAYBE it won't be this time!
I need help.
I think it'd be alleviated with a "mass search" button. Your characters stop, maybe do a 3-5 second animation of everyone fanning out and looking through things, and then you get the loot from ALL the containers and bodies in the immediate area around your party. Saves you the time from opening 30+ containers just to find 3 gold. It'd also feel a bit more organic since it makes no sense that only your active character is ever searching for loot.
