As a feature to developers, and even some old clients, a module that could clean the database, by a selection of filters, for example, front-end/language, user, creation date, end date. The selection list could be similar to the module list on the user module, for example, active it just for a specific module, to a specific category!
This would also come in handy for cleaning the database from testing data!
