Sathya (our fantastic GSoC 2011 dev) has been working on improving the display of information that we can glean from Tor via the control port interface.
You can see the results of his work (including an initial screenshot) so far here: http://gsathya.in/blog/?p=66
We would like feedback from Tor/Vidalia and Orbot users out there on what data from Tor that you feel is useful and necessary both as a general case, and perhaps what might be more relevant in a mobile context.
One case to consider is that in mobile, we are constantly losing our IP connection, switching from 2G to 3G to Wifi to no service at all. What information does Tor produce that can help the user understand better the state that Orbot is actually in?
We are also trying to consider three modes of display: the main screen "dashboard", a full screen detail view, and background notifications that alert the user to important state changes.
Thanks!
