I don’t know how to describe this, so let me tell you about my own experience…
When I’m creating an object relationship draft (a lot of simple cards and a lot of linking), I have a hard time organizing my canvas, but creating a whole bunch of notes and switch back and forth to add links is just too tedious, as each card doesn’t have much in it. Mostly just a descriptive name for each card.
Also in situation where, for example, 10 incoming links to a side of a card, and those outgoing cards are spread amid a bunch of other cards, but moving those cards around would completely ruin the layout…
