 - **Importieren** (☰-Menü oder Datei ins Fenster ziehen) – **PDF**: Jede PDF-Seite wird eine Notizbuchseite mit der PDF-Seite als Hintergrund. Hochformat-Seiten werden DIN A4, Querformat-Seiten (z. B. Folien) bekommen eine Querformat-Seite ohne leeren Streifen darunter. Beim Hineinzoomen werden PDF-Seiten schärfer nachgerendert.

Portrait pages become A4; landscape pages (e.g. slides) get a landscape page without an empty strip below. When you zoom in, PDF pages are re-rendered more sharply.
