this is honestly just a convenience suggestion. i know all those things exist, but im very lazy. greed is the most harmless of all the skills that is available to anyone. as i said, we have autoloot, so we dont even need greed. but for some instances like constellation tower, this is just a faster way to loot the stuff.
also im sometimes forgetful and forget to enable autoloot, so being able to just press a button to loot the items on the ground instead of having to equip the greed item, use greed and switch back. thats 3 key presses instead of 1. in a few years of doing that, you will probably save seconds with that.
