I have my auto pickup configured to pick up certain item types i.e. mostly lightweight ones, but whenever I get to the Casino I close the game and reconfigure it to pick up everything so I can hold down a button, and breeze through the aisles to quickly pick up everything and read a scroll of identify. Afterwards I close the game and reconfigure again. I also sometimes do this after clearing a vault to make sure I don't miss any artifacts or affixed equipment laying around. So I feel it would be convenient to have a quick 'auto pickup all' switch bound to some key. Or ctrl+A could be made to cycle through three options: pickup none, pickup configured only, or pickup all.

Feels like a really niche request, but I'm curious what others think.
