Wish: 'last edited by' field as a column in Top List format

[Eldorado 26]

As a Business user I want to get an overview of last edited notes grouped by collegues.
At the moment I can perform any query (i.e. "updated:day-3" for all changes of the last 3 days) - but i cannot search for a specific author or changer's name. But even if this would be possible, I would prefere to see the "last edited by" information of every note within the Top List. This is possible for the field Author - but not for "last edited by" which is much more of interrest in a team environment.
