"Recently Used" tab in kickoff should be configurable (as it is menu of recent documents in kde 3.5)

this is a security issue as "recently used" tab reveals easy access to the sensitive documents which were recently opened.

It should be possible to set "Recently Used" tab history to 0
Keeping only available under right click "Clear Recent Documents" is a step back in terms of usability, it forces user to remember that before leaving session "Recently used" should be cleared up.

developer absolutely missed the point stating that he is "not in a favor of the "8 billion configuration options that really don't
improve life measurably" philosophy"
