My suggestion http://logos.uservoice.com/forums/42823-logos-bible-software-4/suggestions/509803-make-an-intelligent-flash-card-program-for-vocab-?ref=title to have an intelligent flash card app for Vocab and Bible verse memorization is the highest non-started/non-planned feature on there. Please, Logos.
I would love to have a right-click menu for a word, sentence, or paragraph to "add to flashcard". Then, each day we would come on and be able to run through our repetitions. The program (like Supermemo) would learn which vocabulary words (or memory verses) we don't know, which we sorta know, and which we know really well.
Vocab lists from the textbooks (that Logos has already compiled) could be imported and added to the testable list chapter-by-chapter. Or we could create our own.
Memorization is very much a part of Bible and language study and I would see this only really helping Logos.
If this is done right, I couldn't think of a Greek or Hebrew course not recommending that Logos be utilized as the intelligent memorization software of choice.
So please go check out the program SuperMemo and play with it and see the possibility. I've been using SuperMemo for years and know how perfect the concept would be for Logos integration.
