Okay, I've mentioned this before in the past, but not on its own. I would very much like it if a repository could be added to the account bank giving us a 1-click option to empty our storage bags into account storage. So, for example, I go to the bank and click a button to dump all of my collectibles into account storage.
I would image this would be an added feature purchased through the store for each type (collectibles, ingredients, etc.) I guarantee that there is a large segment of the population who would leap for joy and shell out TP for this feature.
Personally I spend a gawd-awful amount of time on inventory maintenance, especially given my character count, and any features added to help that would be much appreciated. Maintenance of storage bags is particularly difficult because the visibility is somewhat limited. I feel this sort of feature would be a boon.
