I can't find the OP that turned me on to this solution from last week, but I'd like to give him the credit for it. If you are fortunate enough to be an Android user there is an app on GitHub that works fantastic called android-messages-desktop (https://github.com/chrisknepper/android-messages-desktop) It will run in the background and minimize to the tray. It basically takes the android messages web interface and wraps it in desktop applicaiton interface. The developer is actively working on it and is probably wondering why he just got a big spike in downloads!
Anyway, you will need to go the "Latest Releases" and download the Android-Messages-Setup app.
Oh, and you WILL need to make Android Messages your default message app.
