_ bigger card sizes
_ more colours of the cards
_ drop pictures from other apps
_ pictures from clipboard
_ control over the review boxes → see which cards are in one box and moving between the boxes
_ naming the boxes + endless boxes
_ generally more control over the boxes would be nice → maybe like a second folder structure
_ more writing space for the draft while review → notepad style?
_ sounds for the cards would be nice
_ reminders and statistic when you learned
_ stamps for the cards → when learned last + box they are in
