Add a simple activity indicator to the system tray
It would be nice if I didn't have to open and inspect the network view to establish for a fact that an application I'm using is routing traffic through Tor.
At the moment I have to launch a request from the application, then tab over to, or open, the Vidalia network view and make sure there are active streams there.
A small indicator displaying the count of active streams in the system tray would save me this trouble. I think it would also provide useful visual feedback for any user beginning an anonymous browsing session. If they don't see the activity indicator update they know there's a problem. When they first use Tor/Vidalia/Torbutton they will get some reassurance that their setup is properly configured.
At the moment users are blind, and it is very easy to spend some time using a misconfigured torbutton or application before discovering your error.
This is a rudimentary implementation of the idea:
