I have the same problem, being able to target the screen in thirds for wide screens would be really helpful. I have a 21:9 aspect monitor (ultra wide screen), and having a left, middle, right is important. Even better if there was an upper third / lower third option so the screen could be split into 6 windows (upper left, upper middle, upper right, lower left, lower middle, lower right).
