I love the scan feature and use it all the time. It would be great if I could control the file type it generates. Sometimes I would prefer an image file instead of a PDF.
Also, a setting in addition to whiteboard and document and business card to consider might be "screen" for capturing say a PowerPoint slide during a presentation.
I think you used to be able to save as JPEG but the feature was removed? I'd like it back so I don't have to convert PDFs to JPEGs all the time.
