When the handling of edit conflicts on busy pages is good, editors can Reply without even noticing that someone else had just replied to the same comment. Should we notify them when this happens? Would it be possible to differentiate between a relevant edit conflict (same conversation) and edit conflicts elsewhere on the page?
Two options seem to exist:
- Display a warning pre-submit that changes have been made, in case they want to check what was said before posting their own.
- Display a notice post-submit that other edits were made.
In either case, we're sort of limited in that it'd be nice if we could show people the actual edits made... but there could be an arbitrary number of revisions involved, and highlighting new-comments isn't a thing we've worked out yet.
