Organize Button:
I'm sure other games have this feature but the one that comes to mind is Final Fantasy II (US version). At the bottom of a lengthy inventory bag there was a button: Organize.
This button would organize your inventory into logical segments. All pots organized in one space. All weapons in another both in ascending strength.
Having this function in my ingredients bag would be a huge plus! Click -- all shroud mats and house C mats are now organized.
