@poritsy: Very good point, but given the full outliner's power to organize information, it is a much better platform for notes. OmniGraffle's general goal is to compose and export diagrams and flowcharts. OmniOutliner's primary function is to allow fast entry, organization and reorganization of hierarchical information. Given that goal, and the fact that it already supports in-line images, a "quick sketch" input seems simple and natural. It seems so trivial that I would expect Apple has written such functions into their iPad API.
