Some times the User wants to open the "Service Task" Tab everytime he opens a Case.
On other days it would be better, that the system opens by default "Post, Activities" Tab. everytime he opens a Case.
......

It would be nice if we can have a "pin" next to the each Tab Name and depending on which "tab" has actually the pin set the system knows that form now one this tab is the default tab when opening a Case for this user.
Until the pin is set at a different Tab.
