I've been doing mind mapping using excalidraw, but it lacked an easy way and visual way to link cards. This Canvas solution might simplify things a bit, though I wonder how much "freeform", unconstrained doodling I will be able to do using this. At the current point using simple excalidraw diagram might still be preferable.
