It used to be great. But now, since the chat heads became square & I can no longer easily add people to my convo when using the "Bubble". I have to open the app itself then select the ones I want to float along. Interface for easy chatting became harder instead, also the "Bubble" feature has a lot of bugs, for one is it automatically opens your new messages from the app itself & will still remain unread in the "Bubble". It's too annoying because the people I talk to kept thinking I just seen em.
