Should add, Under Edit menu, General Preferences, you can Launch to factory state.  That would be a good start to using a Camera Dot.  That way you have the default cameras saved in a Dot.

Modify the studio anyway you want, use Edit menu GP, to set your Preferred State, and then Launch to Preferred State.  You can use the UI Dots to save up to nine User Interface settings.  Same with Camera sets.  You can use the Poser Library to save cameras too, and Select Subset to save individual camera settings.

Be Well,
