     - indicate also the command that we're waiting on, maybe something like the first three characters (followed by ellipses if truncated), e.g. `pwd <spinner>` or if the command was `echo $PATH`, then `ech... <spinner>`.
+- [ ] save reviewed (checkmark) state for files in the diff view too - we already save comments, so the reviewed state should be an easy addition.
 - [ ] diff view: GitHub code review integration after the local review UX is usable.
 	- publish local reviews explicitly: general PR comments, inline line/range comments, review summaries, approval, and requests for changes.
 	- preserve explicit PR identity and reviewed commit IDs; validate anchors against GitHub's PR diff and recheck the PR head before submission.
