I think this has been discussed before,
but I want to bring it up again:
it would be very helpful if we could simply “lock” a viewport, so that no manipulation of the camera is possible.
basically like it is possible inside a layout (lock detail)
eg. I sometimes have to do very precise Backplate matching and I simply want to avoid any accidental changes. somtimes one hits the space-mouse or hits an arrow key when being in the wrong viewport and then things can get messed up.
I am aware that I can save a view and lock the widget, but I think that should actually lock the viewport with that name too.
