[otrs] OTRS simple feature Sugestion

Hi, We've used OTRS for the last 3 years and we're very happy with it. We' re managing more than 5000 customer users and 1000 system users with more or less 50 queues. We've changed things a lot (not in OTRS) and a result of that, is that we have a lot of invalid users/queues/groups. So what is needed is a checkbox on top of every admin page that reads something like: "Show only valid entries", that does just that: when checked just shows the valid entries, when unchecked allows us to work also with invalid/temp invalid entries. Just my 2 cents, Duarte
