Adrian,
I believe that the tab control is your solution. In fact NI put those in after numerous user requests. I have not looked for and example but there may be one.
Using the tabs is pretty easy, just drop one and start adding the controls to the appropriate page. This does not really add any code to the diagram, but is simply a way to clean up the front panel. You can however use the case structure to add some functionality to the tabs. You can probably update your current front panel, but be aware that if auto grow is on you may cover some controls.
