Would be nice to have some form of dashboard and web widget capability within Discover.
I would like the option to be able to create more sophiscated reportlets on a Dashboard, where I can mix and match traffic and conversion metrics on a conversion report, etc. I don't think this is achievable unless you use Excel Client or Report Builder.
Also the use of the web widget is becoming increasing popular internally. I would also like the ability to create widgets off Discover generated based reports as users can track their site performance without have to worry about where to locate it in SiteCatalyst or Discover.
