From Markus Mueller:
MindNode is an elegant and simple-to-use mindmapping application for the Macintosh. It was created with the user in mind and features a very simple and intuitive user interface that lets the user focus on expressing and developing ideas. Nearly no time is required to learn the interface. MindNode is based on the same codebase as the commercial version. While it is still a very powerful application, it misses some of the features added to MindNode Pro that help improve your productivity.
What's new in this version:
- iPhone Sharing updated to work with MindNode touch 2.0 (Pro only)
- Improvements to document handling to ensure better iCloud and Versions support.
- Don’t draw spell checking indicators when exporting a document as PDF or image.
