MindMaple Lite is a mind mapping software that makes it easy to create
custom mind maps with colors, images, and pictures. You can freely place
topics, create relationships with subtopics and mark items with icons,
colors and callout notes.
Each topic can optionally be associated with a
task, which allows you to track task completion, task priorities,
resources and due dates from within the mind map.
The program comes with a built-in library of icons and some clipbart as well as two map themes to choose from.
Other features include support for topic attachments, notes and hyperlinks.
Your finished mind map can be printed or exported to HTML, MS Word,
Excel, image, text or PowerPoint format. The Lite version does not offer
PDF export, however you could use one of the many free PDF printers to export to PDF via the print dialog.
