If you mean you want to see every reply to every reply in one big scroll I think that’s too much. Twitter seems to have found a sweet spot, but I can’t tell exactly what their ruleset is for which replies to show, how deep, and how to sort.

Maybe it could just show the username and allow an option to expand more. The issue is, you can’t even tell if a note has replies beneath it yet, so you won’t see it unless you tap on each one individually. I think this is a challenge to be solved. No Nostr client seems to be doing this well yet.
