Would it be possible to modify the custom list adding routines so that they automatically filter out duplicates that already exist in another section of the same list?

ie. I make custom list with "section 1" and "section 2".

I add the following words to "section 1": 够， 猫， 鸟

Then I add the following words to "section 2": 住， 王， 鸟. Skritter could detect that 鸟 already exists in "section 1", so wouldn't add it to "section 2".

I ask because I was hoping to generate vocab lists from chapters of a book, and prevent duplicates from previous chapters showing up.

Or if there's a better and/or existing way of doing this, I'd be interested in that too.

Are you concerned about studying words too often? That's not a problem; Skritter doesn't have you study any given word more than you have to, no matter how many times it shows up in a list or in any of the lists you're studying. It would slow the list editing process down to have the system check for duplicates throughout an entire list, so it's probably not worth that cost.

Thanks Scott. It was mainly just to keep the lists clean and make it clear what the new vocab in the chapter was. I think I'll just pre-process each section to remove duplicates before adding it into my custom lists sections.
