One thing I do everytime I post something to sell in the CS is I look at my inventory, then search for that item to see what currently is listed and their prices.

I suggest on the sell page, when you have the item highlighted you are going to sell, there is a button that will take you to the CS with the necessary information already filled in.

So, let's say you are a Dex character that is selling a Fury Sword, lvl 51

You would go to your sell tab, highlight the sword, then press a button that you can call whatever, maybe "See current listings"

Pressing that button would take you back to the search CS page with the following items filled in:
lvl min 51
lvl max 51
item type pink
weapon selected
uncheck show usable items only
in the search box, you would put Fury Fighter's Gemstone Sword (correct me if i'm wrong on the exact name).

The results would be displayed in ascending order on price.

This would make merchanting a LOT faster I would think.

Let me know your thoughts, and forgive me if this has been suggested already
