What they're trying to do sounds great... but I wonder how well they really know their user base...
Scheduling: Without basic feature like scheduling, I CAN'T even test them out. Most "power seller" sell the same items over and over, so it doesn't matter how much I love the interface, if I have to sit there manually launching the listings myself, it's just not going to work...
Inventory management: The idea is nice, but guess what... I'd say 80% of the successful eBay seller will branch out to other platform like amazon & their own site. If you're only monitoring my eBay inventory, it's pretty much pointless... because the idea behind monitoring inventory level for eBay seller is so they don't over list and piss off their buyers, but unless it's synced up with my other selling platform, it's not going to do me any good...
