Things I would love to see added or questions answered are:

Google Checkout (Paypal seems to be always raising their fees)
This ability to "automate" the auctions. (Example: For me to cue up a bunch of auction items one after the other. Once one auction is over, the next auction begins. This would also allow you to feature "upcoming" auctions that aren't live yet.)
Does the auction "close" time get extended with last minute bids? I like how the plugin will email bidders saying they have been outbid, but will the auction extend in order to give participants a chance to rebid?

I also like ovidiu's questions, especially about the verification of accounts.
