If I could give minus star, I would not give 1 star. I would give (minus 5 star).Because in your last updated, we can't see any messages popping up along with the chat head instead it says that 1 have new message, what if that message is super important that only a glimpse of chat head and content is enough. i suggest you should make an option on every conversation to turn off, on that feature. i hope you did this suggestion.
