Google Combines Hangouts Conversations and Text Messages From the Same Sender

In the recent update for Hangouts app, text messages and Hangout conversations from the same contact are neatly merged into a single thread, allowing you to send notes via either method. And to be able to distinguish between texts and hangouts, the two sources are color-coded, and you can separate them any time you'd like. There's also a split in the contacts list for quick searching: folks you chat with on Hangouts and phone contacts that you keep to SMS. For easy access, there's a new home screen widget and improved quality for video calls.
