Everything that worked great in Hangouts, works terribly in chat. I don't know how you go backwards when you had such a great example in front of you. Picture sharing, Gif attach, program load times, separation of spaces and chats, and the over all UX make this experience worth writing this feedback. Build your own standard Google and for the love of god practice some quality control on user experience without sacrificing the opinion of the billions of users before you decide for them.
