I realize this might be too big of an ask but anyway…
I’d like the ability to add a comment to a reply that isn’t part of (inline with) the general discussion. The distinction being that comments wouldn’t advance the topic. They only address some point about a particular post. I can think of number of uses. Here are a several:
- Correcting an inaccuracy in a reply
- Disambiguating some point or fact
- Adding links or other supporting information without stretching out the discussion unnecessarily (Acting like a footnote)
- Administrative comments
It would be especially nice if these could be public or private (visible only to the commenter and author of the reply). But I think the idea has merit even without the ability to make them private.
