It is very easy to get a floating button of Hangouts so that you can use the app from any window. Other desktop messaging apps may not allow you to do such thing but Google Hangouts does it smoothly. Instead of shifting windows, wouldn’t it be nice to have a portable messenger in our desktop so that we can access it from there only without switching through tabs again and again? If we get any message in chat, we may get desktop notification, but there is no way that we can reply right there only. To chat with someone, either we need to open Gmail or sign in to Google Hangouts website. We can do video call, phone call (charges may apply). This allowed us to stay away from getting distracted by email. Recently Google separated Hangouts as a standalone website with beautiful backgrounds and easy interface. Google Hangouts became the best place to connect with your near and dear ones on Gmail. How To Enable Transparent Mode On Google Hangouts On Chrome
