Can we get better a vendor UI already?

[Astrahime]

With how much junk the game throws at you, the vendor (and retainer) UI is terrible... It takes forever to navigate and it's often very laggy.
Especially when you get into gathering and crafting, invetories fill up fast and managing and selling is a big hassle, eventhough many games have solved those issues years ago.

Am i the only one that is annoyed by this? Some more cynical people might say they leave it intentionally as is, to make you spend more time in the game.

For reference i went and sold a full inventory of junk, which i bet a lot of you can relate too, and it takes over a MINUTE, which i think is unacceptable. I get 4 errors in there as well

You realize that in the few frames between selling an item and rightclicking it shows that you're using a modded client, right?
