Exactly. The dynamic history variable in this case.

- The database table "notes" references the table "people"

- User edits the table "notes" and wish to re-assign the note to
  another person; pressing up down brings back the history items for
  that specific table, and the variable becomes automatically defined
  as `people-history'

- now imagine hundreds of such variables and they grow each week
  dynamically whenever some new table gets added;

Larger problem is the mixed history causes problems, so this way there
is no global history.
