I don't know if its just on my setup, but when I do a quicksave with F5, the camera is suddenly outside the hiding place, giving me a much better view of the surroundings, while still keeping Tilo hidden.
EDIT: okay, perhaps its not so bad. After the quicksave the camera is a little bit above the container, but the viewport is still depending on the container (hole if barrel, slit if cupboard, etc.)
Playing on version 6.50 currently.
