+1 to craft from retainer inventory;
But I don't think we need more space. There is no reason to keep fish, bait or crafting materials at all. Everything you could ever want can be purchased or re-acquired with little effort outside of some specific fish.
The only thing I can feel your pain on would be wanting to keep a large variety of skins for glamour purposes, but even that if you hoard smarter, you should be fine with 2 retainers.
..moreover, for the low low price of exactly what you're probably paying anyway, you can get 7 additional characters, each with their own retainers.
(For the same price as the base fee, you can get the benefits of the better account, but you have to pay 3 months at once at a time, instead of monthly.)
