Make the feeds of your contacts an all in one information of any communication. Incoming outgoing text, and incoming outgoing calls, with voicemail received with ability to listen and possibly emails received, with just NEW subject line only with a link to the default app. With the ability to keep your concept and the simplicity of your design, with the information simply flowing down each contacts feed, also with the ability to view just text, email, voice mail, calls. Incoming and outgoing on text and calls if you wish, but overall any and all communication in one place/your app's feed for that contact.
