Frustrating inventory and item stacking, design(?)

[TristanX]

I would like to see the items with sorting options. Also, this will be nice if they add features like the examples below.

All to retainer, or player....
Food
Reagent
Materia
Weapon (only by jobs)
Armor (only by type)
Accessories (only by type)

It takes time sorting them out when the items in the inventory are mixed.
