my comment yesterday about bookmarks triggered somehting this morning – what may be useful would be forward and back buttons in the explorer, so that current, and previous roots could be viewed and reviewed – this should be easy to implement by maintaining the INode tree. having a preference of how many histories would ensure memory isn’t gobbled up.
essentially, the core functions are “starting to happen” now, so I’m starting to have ideas about user will eventually want to navigate this data.
