> - Counter for replies in the root note

Since we won't necessarily have replies locally, we would have to ask multiple relays to count them, and we would need to merge the count results, meaning more relays need to implement HLL first (https://github.com/nostr-protocol/nips/pull/1561). We would then update the reply count only when a note is visible, same as we currently do for updating zap totals and reaction totals.

Otherwise we would have to load all the replies of all the top level notes... which I think is not a good idea.

> - Reactions / Zaps in the inbox notification (with filters/aggregation)

Are you saying that you notify someone when somebody zaps or reacts to their note? I would disable that noise. It wouldn't be easy to track and clear, even though I know other clients do this.

Sounds like a UI project!

Saved drafts for later... yes... could do.

This is stopped because of the rust bug.
