They also need to tag items that are part of gear sets in my opinion. I've sold off gear I had in sets due to too much clutter without realizing it.

This ties in somewhat to the inability to sort the inventory. Also they should allow deletion of items while crafting. Being forced to close the window when it tells you that you can't craft anymore is silly.

I'd also like to see a vendor sell option on the retainer. That idea is one I expect to see the least, but it would be so great to be able to just vendor things on the retainer I decide I don't need without having to pull them into my inventory and go to the vendor.

You can post to the auction house without pulling it off the retainer and putting it on the board. Vendoring from the retainer would be great.

I assume the retainer is going to the auction board and doing it for me hence the lack of a need to go to the board to post it.

Makes sense she could also go the vendor and sell what I tell her to.
