First time I've visited the XDA page of TN, very happy to see "28. announce caller's name" on your todo list!
One thing that has caught me a couple times is that TN doesn't do anything when your phone's on vibrate/silent. I spent ages trying to figure out what was wrong before I realised the phone was on vibrate. Would be nice to have a prompt to take phone off silent when activating the app!
Other than that it's great, I'm using this app everytime I drive!
