Condensed Library files containing only lines with Word List words
When you open a Library file, words from the Word List are underlined in green. I like that. It would be helpful to be able to save an additional condensed version of that file, containing only lines that have underlined words. That would then let the user review just the text of an article containing words in the Word Lists. I delete words from the Word List that I now know, so the condensed version would show just the sentences with words I need to learn. I am doing that off-line with Word List exports, but I think it would be a helpful feature online. In fact, it would be even better if, in the condensed version, the translation also was shown over the underlined word.
