Draw answer / Taking handwritten notes
It would be great if you were able to draw the answer with different colors within Mnemosyne. (Like it is possible by using external software like Epic Pen https://cloud.addictivetips.com/wp-content/uploads/2013/06/Epic-Pen-Drawings.png). This would be useful for maths or chemistry.
However, as soon as you move to the next cards your notes will be deleted.
