Feature Request: Cards for Sale Only+

I have just started selling cards on DB. While I love Deckbox overall, the selling area could be improved.

A key change for me would be the ability to designate that a card is for sale only (i.e. not for trade). There are a number of cards I am looking to sell. I really don't want to waste people's time offering me trades for them. I could list them in my profile but this is a bit hokey.

The other main change I would like to see is the ability to change my selling price on the specific page for a card. I can usually see my price in the list of prices at the bottom of the page but I cannot change it. To do so I have to go to my Tradelist and search for the card. Definitely not very user friendly.
