Very Good but...
This is the best SMS app I ever tested
But I have suggestions:
if you had an iPhone you may have used biteSMS and in the quick reply and quick compose we can see conversation history, its very useful when someone sends you a lot of message in a minute or if you can't remember what you sent before for example.
An other one is to add iPhone emojis because android stock one's arent beautiful and a lot of people love iPhone emojis. Thank you.
And finally custom notifications per conversation (mute conversation, custom vibrations, custom LED, custom ringtone)
And maybe chat head s like Facebook but it would make the app not light (maybe a plugin)
Thank you very much for this app and for reading this message
