Field notes
The desktop workflow is organized around sheets, scales, layers, and revisions rather than general-purpose document reading. The site describes background rendering to keep panning responsive, autosave recovery, and markup codes that remain consistent between the list and exported files. It also links a browser stamp demo, while reserving batch stamping of larger sets for the desktop app.
