Here are the major changes I would like:

1) If I click on "Call with Skype" and my Skype status is set to "offline" The app should change my status to online (or at least prompt) and make then make the call. As of right now it just throws an error saying that you're not online. From a UX standpoint is unacceptable.

2) The necessary "+" and country code is should be fixed by setting a default that can be used for contacts that don't have one. Moving all my contacts from Outlook was a nightmare because of this.

3) Using DTMF is incredibly painful, I'm not sure why this is such an issue.
