I don't know if you can patent your process, but...
I think I would run out and buy the first dishwasher that featured and window! So glad you did this. She is beautiful.
I wonder how long the lunkheads at GE, LG, Whirlpool, Miele and Asko are going to take to figure out that a window in the door is THE thing. With all those republican richies out there spending money like there's no tomorrow on kitchens and fixtures for outdo-ing the Joneses, windows, as we're seeing in washing machines, would skunk the competition.
