Tab Control

The request is for the administrator to be able to Turn On/ Turn Off Tabs on a per project basis. I would like to provide my clients access to the project site, but there are some features I don't use which I would like to turn off in order to reduce confusion.

Dashboard | Tasks & Milestones | Calendar | Meetings | Documents | Timesheet | Reports | Forums | Users

For example, since Timesheet is not fuctional enough for my business, I would like to turn it off.
