Cue the org-mode brigade! (Of which I consider myself a member.)

I haven't used FreeMind specifically, but when I hear hierarchical organization with folding, I remember the rabbit hole that I fell into 20 years ago...and still haven't climbed out quite yet. From Shadow Plan[0] on Palm OS, through so many others, and landing at org-mode for the last decade or so.

Yes! Shadow Plan! I used that, too. Used it to organize my learning material. Then, I converted the outline to flashcards in SuperMemo.
