I already came across the steps for "moving the Window buttons" (it actually may have been an article by you elsewhere). Anyway, they work in general except in one instance at the very top of the screen (which the text remains hidden or shows a title or whatever), when you move the cursor up to the top left corner, the buttons are still there. But for every folder or app such as Firefox, the buttons are on the right side (where God intended).
I also use Ubuntu Tweak. It was great in 10.04/10.10 and earlier. With Unity, it no longer supports as much as it did, which is a disappointment. It appears to be more of an I/F to Computer Janitor rather than the "old Ubuntu Tweak". I believe I installed it from either Synaptic or the Software center, don't recall which off the top of my "receding hairline head".
