I like the idea for wish list, but think the shopping cart could be tricky as thinks could sell whilst you are pottering around the search interface.

I am still unclear how the price history works (maybe someone can clear this up), is this available to look at from your own retainers interface or do I still have to go to the search menu to check prices ?

If its the later I hope they plan to allow us to check prices from out retainers as this is the most time consuming thing for me right now.
