Oh this piques my curiosity, big time! There is a large gap in software for non-linear thinking/sketching. It's not obvious for tasks that require linear thinking, like programming, but when you are trying to explore solutions in an fuzzy problem space, something along the lines of TreeSheets is certainly useful.
