im confused. When you select gear doesnt it do just what your asking? if im equipping a main hand weapon it shows only the main hand weapon gears that i have.

What i want is something that makes me sell all my stuff to NPC like i check 20 items and then select "yes ready to sell" then i sell 20 items at once. that way i do not have to wait for the lag/loading with each item for 100 lines....
