If you are referring to this:
It will change the active window color, but not the inactive windows and is far from the features we have known since windows 3 for controlling the look of windows. I fully understand that we may lose some features for things to move forward. Perhaps you have not had much experience with eye strain while programming for 8 hours a day, but this is a real concern for me. Bright white windows in your peripheral vision can most definitely be painful, but I'm glad you don't experience this.
"I hate tiles", this is true and is my personal opinion. I am glad that you like tiles, I just have no use for them. I use windows for work. I am required to use windows for work. I do not like anything that distracts from my ability to do my job at peak efficiency and tiles are one of those things.
