eBay doesn't want you to be able to sort your list of items for sale by the number of views those items have had. We disagree!
This is a little side thing I put together to allow sellers to be able to sort by Views in the seller dashboard: https://www.ebay.com/sh/lst/active
If you find it useful (or not) please leave some feedback. I'd be interested to know how widely it gets used.
If you find issues, please let me know, I'll do what I can to fix them.
