The program features a convenient tabbed interface letting you manage several projects simultaneously and insert several icons such as flags, signs, faces, and more that will help you emphasize various aspects of your ideas.
Freeplane supports HTML tags such as hyperlinks and the customization of background colors, etc. You can insert images, export your maps as image files, even protect them with passwords.
