No we dont need more retainers, we need a gather-ables/craft-ables bag(just like the armory chest for equips), that has enough room for 1 stack of every regular and its high quality version of the item.

I want to be able to craft anytime not just when I am by a summoning bell, This impractical right now, there are far too many craft items. Also having it as a separate bag that always on you helps when gathering also, since you will always see what the quantity of the item you have.
