Hi, I'm building a cross-generator comments wall that merges feeds from some generators into one custom feed.

Reading works fine (getMessages + live onLoad / onComment), and posting top-level messages works fine via a hideComments: true embed.

But there's no way to post a proper reply from my custom UI so it shows up threaded on its home generator.

Would you consider one of these?

1. com.submit(text) has no reply option. The underlying postMessage({type:"trigger_programmatic_submit", text, ...}) also has no replyingTo field.
2. Or an embed hash option like replyingTo: "<messageId>" to pre-fill the quote UI while keeping hideComments:true.

Same issue for the 🚩 flag button — the embed has reportMessage (/api/reportMessage), but none have a parent bridge. Would you expose e.g. com.report(messageId) / com.block(publicId) or matching postMessage types?

Either would unblock threaded replies + moderation from a custom feed. Thanks!
