Has anyone figured out a way to change the images displayed in the top-12 favorites on the main page of the Web app? Currently, they're each a snapshot of the top-left corner of each site, but some of them look pretty bad. I tried going into the favorites menu, and editing the icon, zooming in on a logo, etc, but they still don't show up on the main screen. It would be nice to have logos similar to the default ones that came preloaded - facebook, myspace, etc. any ideas?
