Selling extra "worthless" gear in inventory all at once button with vendors

[Elixer(S54)]

Hey there. Elixer from server 54. I liked something I saw in another game. It gave you 2 options for selling items to NPC's. 1, sell 1 item at a time. 2, sell all (unbound and "worthless") items to the NPC's with a few clicks. Say, in this games case, blue or green or white gear. In this other game, whenever you chose this option, a separate window would pop-up so that you could take gear out of the selling window. If this was implemented, it could save folks with slow connections (like myself) 5 minutes each time they stopped at the NPC to sell unwanted dungeon/mob dropped gear. What do you guys thing?
