Profiles: Posts / Replies tabs. Replies were mixed into a profile's list, tagged "↩ reply" — now Posts (the default) is what they posted and Replies is their side of other people's threads (NIP-10 replies, NIP-22 comments). Profiles load thirty mixed notes a page and older pages only on scroll, so a tab that holds few of its kind (someone who mostly replies, or never does) fetches older pages by itself — five at most per tab, so a person who never replies doesn't have their whole history paged through. tools/profile-replies-test.js; profile-feed-test waits for rows (the tabs come before them; the old "Latest posts" heading only appeared with notes in hand).
