I like having my Picasa hosted pictures in Flock's Media Bar, but I don't really need the photo uploading capabilities because, oddly enough, I use Picasa's software locally on my computers to manage my photo albums.
The method for logging in and checking for unread email seems a little buggy still, so I removed the email button from the toolbar and stashed the icon for the Gmail Manager firefox extension there instead. Previews are better, and I can do more with it.
The one email related feature that does work now is the Share this Link button. Enough said.
