Also does anyone have plans for nest boxes where the opening is inside the coop but the box is outside?
That would be simple... Just build the boxes on the outside of the building facing inwards with holes cut in the side of the building for the hens to get in. I would extend the top box much higher than the inside hole to allow a sloped hinged sectioned roof so that rain would run off of the top of the outside, no other birds would roost on it, and you could lift up each section to reveal then nests below and their corresponding eggs. I would keep the roof sections limited to one or two nest boxes at a time, though, because you don't want to be getting eggs out of one nest box while having the hens fly out of the other nest boxes.
As an alternative to having the roofs hinged, you could also place moveable panels on the rear of the boxes so that you could see and reach into each nest to retrieve eggs from the outside.
However, you make it, make sure that you have the roof lids doors secured well so that smart predators like raccoons can't open them at night and get into the coop through your access ports.

ETA: if i had more than one nest box and one went broody would i still have to seperate her from the others?
Not necessarily. The broody hen would usually protect her eggs. However, it might be advantageous to do so, especially to relieve her of some stress and to make it where she could get up for a few minutes to eat and stretch her legs without worrying about the eggs or chicks. It all depends on whether or not you have the capability to do so.
