It is not clear from the feature set if they have added create/edit/save support for MindManager in SharePoint libraries but they have treated SharePoint as a data source for maps. Even a SharePoint site structure can be imported into a map. This was something that I had attempted using the MindManager xml file format and a Data View Web Part http://www.wssdemo.com/Blog/Lists/Posts/Post.aspx?ID=438 . Their solution is much nicer…
But it costs.
Mind Manager can now link directly to SharePoint Task lists and create dashboards as well as consuming search results to provide related links in the map.
