Comments on the running app

Pin a comment on a button, a heading or any element of the running app — it stays on that element at every device size, with replies and resolve.

Some feedback is about the app, not a line of code: "this button wraps on phones". Pin it where it belongs.

Pin a comment

  1. In the Preview, press the pin button (or More → Pin a comment on a phone).
  2. Click anything in the page — a button, a card, a heading.
  3. Write the comment and press Pin (or Ctrl/⌘ + Enter).

The pin sticks to that element — when the page scrolls, when the layout changes, and in every device frame — because it's anchored to the element, not to a spot on the screen.

Threads

Click a pin to open its thread: reply, resolve (✓) or reopen it, and delete your own. Resolved pins are hidden — Show resolved at the bottom left brings them back.

Everyone in the project sees new pins and replies instantly. The person whose app is shared gets a notification for a new pin, and people in a thread hear about replies (Settings → Notifications → Comments on the running app).

Editors and above can pin and reply; viewers can read them.
