I'd love to be able to see my comments by version number. When I am reviewing notes and I am on version 8 - I have no reason to see versions 1-7 as well. It is extremely cluttered and takes me forever to find the most recent notes and then check them against my current version.
A simple "Filter by version #" dropdown would fix this and save a TON of time.
To me - the best thing you can do for your users is save them time. All the other features are secondary compared to efficiency within Replay.
