MinDgo v5.0 is now available at the iTunes App Store. This upgrade includes support for Freeplane’s 1.2.18 file format changes and includes additional icons.
Note that MinDgo discards features that it doesn’t directly support when importing files. This means that some features may be lost when a mind map is (for example) created in Freeplane, imported into MinDgo and then exported back into Freeplane. Although MinDgo will support more features over time, the diverging file format and features between FreeMind and Freeplane will make full feature compatibility unlikely.
