MindMap Export Support
One of our users is really into MindMaps instead of Wiki - though they're actually very similar
It would be very useful to him to export our Moin Wiki to FreeMind, for instance
Further, the WikkaWiki engine uses MindMap to represent all sorts of Wiki data - would be a nice addition to VisualSiteMap : )
Note: Although we have no "export a wiki to a mindmap" thing, we do have a MacroMarket/FreeMindBrowser.
