You can leave a comment on any cell in both Logic View and in published Apps.

Click the icon in the upper right of an element to trigger the Comment popover.

You can add a new comment, reply to an existing thread, or edit or delete any comment you authored. You can mention other users in your organization with @ tagging, and they will receive a notification via email.

Resolving Comments

By clicking "Resolve", you effectively "archive" a comment to the Resolved tab.

You can unresolve a comment to move it back to the main view.
