Hi everyone, when we started our discovery for updating Discussions these reply navigation issues and feature requests quickly surfaced:

1. Modern digital conversation tools follow a vertical format vs. horizontal
2. Discussions with many replies sometimes took too long to load or timed out
3. You cannot tag another person with an @mention
4. You cannot quote the person you are replying to
5. There were too many clicks to see and respond to unread replies from the Discussion index page
