I wonder if it may be possible to create a journal of all the operations
on tags: a file where all the changes are registered, with a timestamp.

Two benefits:
 - going through the history to undo mistakes
 - being able to build a diff of two journals in order to synchronize db on 
multiple
   hosts

A drawback may be to slow down the changes on tags, since we add one more write
each time a tag is added or removed.
