I was wondering if anyone has done this, or has a good idea about the best
way to do it? maybe a @script that extends the save command and walks
through the node tree, and looks for dirty nodes, updates version, then
calls save? or could I use or display the date information from the node
strings that leo saves in the source? or is there a better way?!

​That "script" would be an event handler, contained in a plugin, that fired
on either a "save1" event or a "command1" event.  See:
