If you are going to put the effort into changing the hangouts app, here are my suggestions.
1). Fix the random frequent crashes / restarts.
2). Add the ability to delete a single message without deleting the entire conversation.
Removing useful features like SMS integration and merged conversations (especially for #googlevoice
users) is just a waste of time and alienates loyal users.
Maybe later I will rant about how bad sharing YouTube videos recently became, or how schizophrenic the instant messaging ecosystem has become. The Google experience is just getting worse and worse.
And worse. +Bradley Horowitz
