Maybe if they reintroduced hangouts and let me:

• make phone calls
• make phone phone calls with Google voice
• make voice chats
• send sms messages
• send sms messages with Google voice
• send chat messages
• make video calls
• permit all those options (except native sms) from Gmail, the desktop app, and the dedicated webpage
• collate my conversation with people among all the communications methods listed

I'd be tempted to use them again. It amazes me that they made an app that encompassed basically every modern form of individual communication laid out in a clear understandable manner and they just thought it would be better if every feature they offered were it's own app. Now I have to remember which medium I used to talk with somebody and use an app with fewer features.

I miss hangouts.
