The OmniGroup released a new version of OmniGraffle today as well as a professional edition. I’ve been using this software for a couple of months now to design website hierarchies, task flow diagrams, and even some fairly complex screen schematics. The new Pro version introduces an awesome new feature which has been sorely lacking from every diagramming tool I’ve used aside from ConceptDraw, multiple page documents. Another unexpected surprise is the phenomenally slick solution the OmniGroup has created to handle their floaters. It’s reminiscent of Macromedia’s cool new design in apps like Dreamweaver but more Aqua-oriented and a bit more slick. Basically, the floaters can be grouped and ungrouped by dragging them near each other, and expanded and collapsed easily.
More on this when I’ve had a bit more time to work with it.
