Even though mine does not open, I enjoy my kitchen window. It adds light, plus I like to look out. I would suggest also a drawer in the wardrobe cabinet, if you can get one.
I got an outlet on the stove cabinet front for hooking up a hairdryer to use in the bath (door is hinged on the right per my request). It also comes in handy for the electric coffee pot that sits on the stove cover and the cord does not snake from the end by the sink where the stock one is. I also often use it for charging.
Just some additional thoughts.
