Do the options not show up for you at the top? I guess the first option would be the one for you: I can perform searches and sort currently working on applying filters. It's currently not in a usable state, the difficulty has been getting it to look right rather than the actual web service interface with ebay. Once i have the various GUI elements the rest should be relatively easy. However I am confident I can provide just as much features as the Android app plus more N9 specific.
