When switching from table view to tree view, open the tree to the location last viewed in table view. For example, if your viewing path in a document is profiles.merchant.business, when switching to tree view, the disclosure triangles should be open for profile, merchant and business, so you would be placed at the same view of properties/values you were observing in the previous view. The inverse should hold true if switching from tree to table.

If switching to json, the focus should bring you to the last property viewed.
