Windows actually are used for visual inspection in flight in a number of cases. You can actually see markings above certain rows where a pilot or a flight attendant could look out and inspect something. I think the types of things they would be looking for are flap deployment, icing, damage to the wing, gear deployment (though there is usually a window in the floor for this), etc. There's a great YouTube channel called Mentour Pilot that covers a lot of stuff like this, but I can't find his video that discusses visual inspections. https://www.youtube.com/channel/UCwpHKudUkP5tNgmMdexB3ow/featured https://www.youtube.com/channel/UCwpHKudUkP5tNgmMdexB3ow/fea...
