I'm sure this could be accomplished a lot more efficiently, but here's my attempt to add spaced repetition functionality to OmniOutliner 3. The goal is more efficient memorization using the SM-2/SuperMemo algorithm. (I hope I implemented the formula correctly). Flashcard programs like Anki and Mnemosyne are great, but it's tough to see the context of what you're learning, and in law context is very important. Using OmniOutliner, the row text can serve as a question and the note text as the answer. Columns 3, 4, 5, and 6 are used to store the information about past and future repetitions.

I've got more written up about this on my site, along with simpler spaced repetition routines for some other software (VoodooPad and EagleFiler).
