Nostr browser (for apps), outbox and crossplatform I think are the major distinguishers.
Discussion
Even though, I don't think outbox has been implemented yet in notedeck? Just a local relay to sync to, if I remember correctly.
yeah its pretty trivial to add, i just wanted to focus on the android release first
Trivial-ish, there are a whole lot of other issues that can surface in the process, probably not in regards to the UI though, as it's decoupled. So that is good.
Two I've noticed awhile ago: centralization of (and missing) NIP-65 info at relays (could be a whole research project) and a need for broader support for negentropy for greater efficiency with hundreds to thousands of relays to communicate (and not always online).
true, it's probably not that trivial, but i wouldn't even bother to attempt it without separating UI from relay behavior
