Thanks a lot, I remember that thread but it didn't occur to me they are speaking about next major version, I thought it was about another minor update.

This might be a shot too far away, but you know the flashcard programs out there designed for students to memorize Q&A pairs, at least one of them had the repetition pattern customizable, so that you could set first repetitioin to 1 day, second 7 days, etc.
If interested try jMemorize or Pauker, not sure which it was though....

Some shareware authors allow it, but it's not smooth. You have to write them, and so on.
Lifebalance from Llamagraphics comes to mind, but I'm sure there are more.
