Reviews happen on the file itself
When an agent opens a document for review, your notes are now written into the document — as the same <!-- imark --> comments the app has always used — and travel with it. Send the file to anyone and the notes go along. The hidden copy under .imark/reviews/ is gone, and so is a subtle race that could end a review with a stale decision.
When the agent acts on a note it marks it resolved= instead of deleting it: the note stays as the record of what was asked, shown faded in the margin.
The app now notices new versions
Once a day Imark asks GitHub for the latest release number and tells you — once per release — when there is something newer. A version number travels; your documents never do. Turn it off in Settings, or check on demand with Imark → Check for Updates…
Updating is still drag-and-drop: download, drop it over the old one.
If you are on 0.1.0: this is the one update your copy will not tell you about — 0.1.0 predates the check. Grab this DMG once, and from here on the app lets you know.
