Adding documents
Tap + and choose PDFs from Files or iCloud Drive, or open a PDF in Crossleaf from Mail or AirDrop. Files from Files and iCloud Drive stay where they are — removing one from Crossleaf never deletes your file.
"No text layer" or "No outline"
Crossleaf searches the text inside a PDF. A scanned document without a text layer can't be searched — run it through OCR first. Section paths in results come from the PDF's own outline (bookmarks); without one, results are shown by page only.
Apple Pencil
Open a page and tap the markup button. When you tap Done, your drawing is saved into the PDF, so it shows up in other apps and on your other devices.
