Retro Messenger (Is there anything else a messenger could need?) (retromessenger.space)

For a few months I've spent my free time working on a C++ messenger. It started off pretty simple, just two input boxes for IP address and port number, more of a fun experiment. From there it started to grow and soon allowed for peers to connect automatically using a relay. For a while it only allowed two people to speak at once, which was good for security but was very inconvenient. Now Retro Messenger allows multiple users to speak at once, sending encrypted files and messages that exist only in memory.

Although there is plenty of things I could improve, I was curious to see if anyone had suggestions or requests for what else could be added. I'm currently debugging a local-logs feature, and I could look into how to implement voice calls in the future. Thanks for your time and feel free to ask questions

I don't really see a market need for this, just use signal. C++ is also a weird language to use in the modern era, pretty much totally eclipsed by Go or Rust, not that you need performance anyway. Or just use webrtc for p2p connections with a standard TURN/STUN relay for network layouts that prevent direct p2p, this can be done pure web or via apps. Already has audio/video and encryption. XMPP and Matrix are also fine. But as a learning exercise, great project
