Window awnings to keep the sun from shining into the house. Take cheap shelving brackets, turn them upside down and obviously mount them on the outside above windows. Screw plywood to them and mount them at a slight angle for drainage.

Tinted Deerview windows. $20.

On my next one, I'm going to put a window sill deep enough so I can lay my rifle on it so I don't have to transition my rifle from my lap to the window. Less movement.
