Custom Font Size in cards

I'd like to be able to customize the font size and the size of the flashcards so they're bigger; when I study for a long time, my eyes get tired. Also, could you add an option so that when we take a quiz, we can choose the number of answers? Right now, we're limited to 4, and I'd like to practice with 5 as well.

You could also add the option to include images and ask questions about specific parts of the image—this would be very useful for anatomy courses. For example: a photo of the brain, and the question would be, “What does number 4 indicate in the image?” There would be an arrow pointing to it, and the answer choices would also be multiple-choice.
