I don't like the two spaces between the maximize and the close buttons.
Ah, because those two spaces haven't always been there I've moved the close button to the left of the titlebar for over a decade, or since I found that with two similar buttons very close to each other I clicked the wrong one half the time. Closing a window when you want to maximize it is not good.
(Even Microsoft fixed the problem in Vista by making the default close button twice as broad as the maximize button.)
