What phone APIs would you like to see into Windows Mobile 7 ?

The Windows Mobile team would like to have feedback from developers about phone APIs missing in Windows Mobile. They are looking for answer to these questions:

1. What are the things you wanted to programmatically do on the phone system, that you weren't able to do?
2. From the things that you were able to do, what were the pain points?
3. What kind of phone (dialer, makecall, incoming calls etc) related apps do you write, such as answering phone call and replying to sender with SMS when in a meeting ?
4. What kinds of phone UI extensibility are you interested in, such as changing the color of the text in the accumulator.
5. What kind of technology (managed/native) do you primarily use for writing your apps?
6. What type of phone related notifications (from the notification broker) does your app listen to, generally, such as signal strength notification?
7. What type of phone related notifications (from the notification broker) do you wish your app could receive?
