Paths

•Keep track of path taken with respect to time, so it can be replayed (and added to a workspace as such)•“All children of a node” (not following links that lead back up the hierarchy) is meaningful• Possibly all related• Possibly search results

•If we add some outside knowledge (like, Google is a search engine) we can guess certain user behaviors• Email, Directions (Google/Live Maps), etc.
