I need to be able to scan single page documents, particularly certificates in PDF format. Today was a classic case in point where I had to use another scanning app and then email to myself and then add to Evernote. Most of the people I know need single page PDFs with occasional use multiple page when using their iPhone or iPad. Please let's have a PDF as the default for all scans including for 1 page. You could add a selection button for .jpg if you really think it's important to keep for single page work.
