_ 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
