Ok, after a few hours of testing ive noticed some bugs (at least when using your mod with gwx 1.03):
1. there are some weird black/grey "artifacts" at the horizon when using binoculars (made screenshots but unfortunetly they are all black except the one posted below...);
2. when clicking on watch officer camera moves to the top - like this:
Also it would be nice if second use of F4 would reset the camera to default position on conning tower.
Other than that - great mod
