All,
I was talking on-wiki about an important Flow feature which I feel should be the top priority since its early days. I don't see any progress.
https://www.mediawiki.org/wiki/Topic:S12prb6trf24nhkz — make it possible for users to split, edit, re-assign author, indent, and move other users comments. This is necessary for backward compatibility and also for migration of classic talk pages to Flow.
