See PHI549. An install would benefit from an `--auto` mode on `bin/differential migrate-hunk`.
See PHI505. An install would like a feature which I bargained down to a `!history` command that replays an object over email, for reviewing events if you were `@mentioned` onto something you don't have context on and are off-VPN on your phone on a train. Perhaps see also T11934.
See PHI531. An install would like a way to abort builds for older diffs when a revision is updated. There's some consideration for adding an "Outdated" status vs "Aborted", but this is probably a larger problem which overlaps with PHI533 (timeout "Waiting for Message" builds), run command timeouts, etc.
See PHI512. See T8953. When you receive a notification about an object and later lose the ability to see that object, it is unreasonably difficult to dismiss the notification.
See T13105/T13125. See PHI577. Basic coverage display support, at least, should make it back into Diffusion this week.
