I have 6000 Tier 1 Corkian Amplifiers and the best way I have of storing them is putting them on trade market, which takes up valuable slots, or throwing them in the account banks of alternate characters, which makes them a hassle to pick up and use. It would be great to have a solution for this problem.
In all seriousness, it would be nice to have a dedicated storage for items that are easy to have bulk quantities of. The misc bucket is nice, but it would be much better to have a dedicated "powder keg" or something of the like for powders. I think the best solution would be to have a dedicated misc-bucket type of setup for resources (wood, gems, oil etc), powders, and keys. I would especially like this for crafting resources since they currently can't be stored in the misc bucket.
