PDFx is a workspace like your actual desk: drop PDF files and view them simultaneously on a 2D canvas. - The pages of a single file scroll horizontally, while the files themselves scroll vertically - Produces a single zip file with all PDFs (ideal for mortgage, banking, taxes, audit reports, legal work), or a long continuous PDF file - Acts as an extension of the existing PDF standard, storing spatial 2D metadata without altering the main page tree
