map thaughts over background image
I would like to map thoughts over background images that become active with a particular thought. e.g. when the thought "creativity" is active, I would like to have a selection of background images, which I can move on the surface. e.g. over this background I would like to pin thoughts, as written down on the background image. Whereas when one of the thought is used with a different parent thought, I might want to have a very different background image for that parent thought. I think it is useful if I could have multiple background images linked to one parent thought.
Arranging thoughts over a background image helps to structure the knowledge.
