The moderation module provides a queue of content.
It allows moderators to review all posted content while already published.
Included Ajax based functionality allows the moderators to preview the content and to change status like published, moderated, promoted, sticky without having to leave the page.
A seperate page provides a log, listing all status changes with who and when it was changed.
