Freemind vs Scapple

For the most part, navigating the editor is pretty intuitive - moving around is done by clicking and dragging the background, clicking on nodes will expand/collapse them, dragging and dropping in files will add them, etc. It also offers shortcuts for power users. For example, ctrl + up/down will rearrange ideas up/down, alt +up/down will zoom in/out, etc.

Freemind offers many choices when exporting. It allows exporting the project as Java Applet, Flash file, Open Office Writer document, picture (png, jpg), PDF, SVG, multiple variants of (x)html, among other options.

Freemind allows quickly copying over structure of the mindmap as a bulleted, tab-indented list starting at the node selected. It can also take a bulleted, tab-indented list and create a mindmap from it.

A user-contributed patch is available that adds fullscreen mode to FreeMind.

Works on Windows, OS X, Linux, iOS and Android.

Freemind accepts drag-and-drop for any kind of file, URL or command as part of the mindmap. Files it recognizes, like images, will be displayed. Other files will open in a separate, appropriate application. URLs, links to folders, and executable commands pasted in will be recognized and turned in to clickable links.

You can customize your styles, background and font as you wish.

It gives you the freedom to use visual thinking without the hierarchical rigidity of a mind map.
