This makes sense, and I agree that a native drawing functionality would be a beautiful thing.
But in terms of the name, canvas, I think also of the name, Obsidian, and the expectations that it too provokes. As software, it helps us form our ideas like obsidian, but in a more symbolic way.
Perhaps we can imagine that the arranging and connecting of nodes (whether they be notes, cards, images, videos, websites, canvases, etc.) is the artistry we collectively mark our canvases with.
Thanks for helping me see this in a new light. And perhaps your honest observation will help the cause. It truly would be sweet to be able to instantly generate an embedded sketch (whether in a note or a canvas) directly from within its host’s confines.
