There are two ways for a reviewer to leave feedback in Differential:
- start a thread on a particular line
- leave a comment on the ticket.
If someone posts a question to the ticket, I'd like to be able to respond specifically to that person/that question the same way I could if they left a line comment. (The reply should appear near the question, the person who asked should be notified of the reply, and either party should be able to mark that thread Done.)
Otherwise, ticket comments can be hard to follow, as multiple reviewers ask different questions, and the whole timeline is interspersed with commits.
