Is such a thing even possible? I know the moddig tools for this game are much more limited than other games that have this functionality. This type of mod might be handy for people that go on harvesting marathons to sort out their bank afterwards.
Didn't think it was since something like this would already be out if it was. Thanks, though. This will keep me from searching the web for an impossible addon.
there is a bag you can get from completing a quest that only holds harvestables and it has 36 slots! I love that bag being an avid harvester myself the harvestable materials go directly to that bag before all others no matter what slot you have it in. The bag is called Wantia Artisan's Satchel and the quest starter for this bag is the class specific quest in the village of shinn see here for more info
