The only item-related issue I have is being unable to see what my retainer is holding, without going over every slot. The upcoming sort function should help a little, but we still have to dig through our retainer inventory to see what we have. I've been slogging my way through crafting this way for awhile, and it is getting a little easier as I clear out the rubbish. Having a full retainer inventory of crafting mats was a nightmare though.
