I subscribe to too many RSS feeds. As a result, there's always a new feed to read. In order to help keep my concentration, I try to turn off all notifications (new email, twitter, etc).
It would be nice if there was an option to stop the system tray icon from changing as the status changes.
I'd still like to keep the system tray icon around, I just don't want it to indicate that it's busy, refreshing, or has new items.
