Everybody knows the struggle of thousends of materials scattered above all characters and to switch if you’re looking for a certain material, or even flooding your inventroy with lots of ‘trash’ materials.
Lot’s of known MMO’s already implented such feature (the far best was in GW2). Honestly it’s just a act of copy/past.
I don’t mind if it is only available for Token users, or if you have to buy a ‘expand category’ item from the TP shop. I know there’s a addon roaming around that let you browse through all your character inventories once scanned. But i’m more annoyed by the amount of materials and quantity in my inventory. Especially when i got to HG or simply farming and within a few seconds my inventory gets crowded by mere 5 pieces of armor/weapons.
