I sell a lot of items over ebay and the mobile ebay is pretty limited for sellers. I would like an ebay app that allows sellers to view the following:

1. easy log in (or always stay logged in)
2. # of people watching their item
3. # of views item has received
4. ability to relist item
5. ability to respond to messages and best offer requests

That's about it...I'm sure there could be some buying features added as well!
