Every comment becomes a first-class object with an owner, a status, and a link back to the exact frame. Reviewers resolve threads in place; designers export a clean decision trail when the file ships.
Click anywhere on a frame to anchor a comment to real coordinates. The pin binds to the node, not the pixel, so it survives the next layout pass.
Every thread gets an owner and a state — open, in progress, resolved, or won’t fix. The state machine is deliberately tiny so nobody has to learn it.
Ship with a Markdown or CSV log of every decision and who made it — the artifact that turned out to be why people actually installed the plugin.
A single-page pitch for the plugin: the problem in one line, a live annotated frame you can poke at, and the install button. Written to be read in under thirty seconds.
