"Sort By...", "Compare" option in inventory, retainer, or markets.

i'm sorry if someone already mentioned it before.

i'm really frustating about organizing my inventory and my retainer. maybe the "Sort By" option really helps a lot. like by Type, Amount, or anything else.

and another problem is, there's no Compare action in Market Board or inventory/retainer itself. it's really difficult for me as a PS3 users to compare the bonus stats on each weapon/armor.

and there's no sign if our items in Armoury Chest are equipped by other gear set. So sometimes i accidentally convert it into materia or sold it at NPC.

or i don't know how to do it? :p

thx
*sorry for my english. :D
