group words to learn by text of origin
suppose you want to read a book to learn a new language, as you translate unkownn words they are added to your word list, and when you study they will come up following the SRS principles; however, other words from other texts will also come up. This is inconvenient if all you want to do is being able to understand a particular book.
Hopeful this is not too bothersome, otherwise this is a great website.
