MindNode Pro includes the same features as the free MindNode version, and adds several new features that help improve your productivity.
Image and Visual File Links. MindNode Pro 1.5 adds the ability to add images to nodes and preview the content of a linked file directly on the canvas.
mnp-cross-connections Cross Connections. Cross Connections are secondary connections and unrelated to normal branches. They allow to visualize a relationship between any two nodes on the mind map, which are otherwise unrelated.
Folding. Collapsing a sub-branch is as easy as creating a new node in MindNode Pro. Simply press the option key, and the node well turns into the folding icon, allowing you to fold a sub-branch.
