Hi, I think you should consider to add a shortcut for cycling over all the saved point of view like Ctrl+Shift+R or something else :

1- Ctrl+Shift+R => First point of view in the list
2- Ctrl+Shift+R => Second point of view
... (etc.)
X - When all the point have been seen => REturn to the first Point of View


You could also add a shortcut for the 10 first one with Ctrl+Shift+[0-9].
