Cloning Dashbard Tab
One answer
This feature will be available in RTC 2.0 (or any product with dashboard from Jazz Foundation 1.0) in the form of copy & paste support. You will be able to copy & paste viewlets or tabs, however it is based on a relatively new browser feature (global storage) so this will not be supported in all browsers. (I know that it is supported in both IE8 and FF3).
