Why can't people make buildings with normal windows anymore?
You know windows, right? And you open them, and there's a very subtle and intuitive arm-like device attached to the bottom of the frame which allows you to choose how far open or closed you want that window to be and then HOLDS IT IN THAT POSITION...yeah? Why don't they make those for windows anymore?
(sorry, I was worried Theo might have run out of minor issues to rant about)
