More than more retainer I would like to have some overhaul for specific types of items. I have 6 retainers, 2 of them are just for housing items (and most of them are from seasonal events). Just having separate chest for furnishings alone can save the day.

Also I do like the way crafting works now (it is quite immersive), but with new expansions incoming there're just too much materials. I, myself, only gather what I need in nearest future (except some time restricted nodes), but I can imagine the absolute mess in retainers' bags and pain of players who craft on daily basis and always need a variety of materials at hand. I don't think there's a need for reducing variety of them, but maybe it's prossible to arrange something like a special store box for them, even if only in Inn room (considering we can't have dresser in housing)?

Also, all the Trial tokens, Raids parts, Materia Clusters... please, please, can we have them as part of "Currency" tab?
