[Few of the Q/A]
Q: Is there any plans to make user ID system, so that we can add friends without knowing the phone numbers?
Ans: Yeah, we're working on it!
Q: Hi, is it possible to backup chat history?
Ans: Thanks, we know this is a big deal and think about it a lot. We're working on ways to do it that would be privacy preserving...
Q: These things would really make the experience for my family and I complete
Support for backups and transfer on Android. Not manual, but automatic like iOS
Support for ChromeOS via Android Tablet support
Support for simple markdown like bold, strike through etc.
