Mind mapping and idea tracking
with other mind mapping software packages, FreeMind allows the user to
edit a hierarchical set of ideas around a central concept. The
non-linear approach assists in brainstorming new outlines and projects
as ideas are added around the mind map.
You can use FreeMind for just about anything - keeping track of projects, a collection of notes with links on some area which expands as needed, or essay writing and general brainstorming.
