Cards should appear as if One is scrolling through a PDF

1 . Let suppose I highlight a PDF and generate flashcards. Now I want to practice them in order. The cards should unfold as if they were being scrolled down on a page in the PDF and not as separate cards. If the cards have different timelines associated with them as I may have marked some of them good, hard, again. The scrolling should skip cards with longer duration but yet should be visible.

2. Hint option should be added to image occlusion as well as cloze and other cards just like Anki.
