Image Occlusion is a simple but very useful feature. With Image Occlusion, I can draw a box to cover up labels on a diagram. If I tap on the box, the box becomes invisible and the answer gets revealed. If I tap again, the box becomes opaque and the answer gets covered up again.

There should also be a button to cover up all of the answers at once or reveal them all at once. When I’m done studying for the day, I want to cover up all of the answers, in order to pick up my studying next time. When I just want to quickly read the information, I want to hide all of the boxes at once to show the answers.

Also, please let us zoom in on the flashcards because the answers can be hard to see.
