ReliaBilt at Lowe's: 6' Steel French Patio Door Unit with Grilles and Blinds Between the Glass
This is a random one, but very functional & stylish. I hate the way blinds on a french door looks but most people want the privacy so lowes or home depot has these units you clip over the window that have the blinds inside between glass so the blinds stay neat looking & slide up with easy when you want to let the light in. The unit also blends so well with the door. This is also great if you have kids or like me a dog that stands up by the door so they blinds can't get messed up. Much cleaner lines.
