Navigation bar with changes history?
Alessandro pointed that, in the past, a "navigation bar" was allowing navigating through the full set of changes before decide to save. Basically, starting from the top level table, one can go down in more than one "subtables", edit the content, be able to navigate back and forth the changes and at the end decide to save. The possible re-implementation of this navigation feature has to be decided keeping in mind the actual needs of the L1 DOC.
