We all have several thousands of crowns worth of materials in our inventory, the only problem is that it would require several thousands of clicks to sell them.
I propose that a new way to sell items be implemented, one that would allow the player to select how many materials they wish to sell to a vendor/stranger, this could be done either by a scroll button or by inputting the number of the selected material you wish to sell. This would allow players to spend more time in game and less standing in front of strangers as they watch you slowly empty your materials into their hands.
NOTE: this idea only applies to materials as the mass selling of armor or weapons could end up selling off something with a nice UV.
