Highlight and Flashcard combination

Consider incorporating the most useful concepts from competitors including UWorld and Anki. From UWorld, consider adding highlight tools so when we review old tests we can look at specific points. Also please add a flashcard feature where you can highlight something from the answer key and add it to a flashcard to review later. And from Anki, consider adding spaced repetition as an option for review of the flash cards so it will help us stick better.
