I would like to suggest a new way to add words based on the characters that you already learn (vs. adding in order of the list).

For example, say I am using the Heisig or Hoenig method to learn characters.

It would be nice if I could selectively choose an option for a given word list that would automatically add words once I have learned all the characters that make up the words.

In principle, this could also apply to sample sentence integration in the future. Add sample sentences from the sentence bank as soon as they contain all the words/characters that I have learned.

I can see how that would come in handy, but it's a lot of work for the server to check through all your auto-word-add lists whenever you learn a new character to see if there are any new words which you can now learn. I don't think is something we can easily build.

If Microsoft makes FDS available to the public some day, could you take a look at the problem again and see if it's doable?

Interesting technology, but not exactly what I mean, even if it were available in App Engine. It's possible to scan through all the records today using Google App Engine technology, but it's terribly inefficient. There are ways around the inefficiency that require a ton of work. Making something doable doesn't make it worth doing.
