User Control Activities
1- Skype doesn't allow to turn off the ringing on incoming call (if the phone is not on silent mode). Skype should allow user to turn-off ringing on incoming call by pressing power key.
2- User last seen time stamp should be in user control.
3- Idle status feature should be a part of user control. Skype should allow user to manage their idle status based on last activity, and also there should be an option to turn-on idle status: after HH:MM:SS or turn-off idle status: keep the status as it is.
