while we have a linking function within the text editor of cards, Iwould prefer to have a simpler way of linking just cards.
Select a card, use contextual menu, add link, draw a line from the selected card to a destination card.
This will only link cards on a “top level” and not specific text blocks. This may be sufficient for several use cases. In my surcease, I am just writing atomic notes for each card. Hence I do not need a linking of block and would rather have a quick and visual way of linking.
