The Omni Group has announced the availability of OmniOutliner 3.8
(http://www.omnigroup.com/applications/omnioutliner/), an update to
their popular note-taking and outlining program.
OmniOutliner and OmniOutliner Professional 3.8 now include Quick Look
support for document attachments, so you can quickly preview files
that are added or linked to in outlines. This allows you to view
large images in your document independent of the document window
size, or view files that don’t display a preview in OmniOutliner
without having to open the file.
Other new features included updated Keynote import support, improved
HTML and Dynamic HTML export, and a number of improvements and bug
fixes.
