Being a student I really miss the feature of flash cards support. Would be nice to have something like a sticky note on the mind map, but only for handwritting with apple pencil. More configurable instruments for writing (lines, marker, erasure size), configurable paper templates - like grid (size and color), lines and so on. Further export of such cards to Anki formats. This is the dream feature for me. Hopefully I am not the only one.
