Plus when the window is maximised you have to move your mouse all the way across the screen to minise or close it which gets very annoying.
Just want to point out that no matter where on the window border you put the buttons, you'll always have to move your mouse all the way across the screen to get to it.
But yes, I think that the suite of buttons should all be together (Or you could put them on the bottom! Down the right hand side! Whatever!), so that when you have multiple windows open, you can go through them all, closing or minimizing based on which you want to keep, without moving back and forth across the screen.
or just give us expose....
I do like the symmetry. I think it is very important to be symmetric because it is aethetically pleasing... i.e. the reason why many people like MacOS so much is because of it's aesethically pleasing GUI.
Also, if the window is already maximized, double left clicking should also be able to minimize it too.
Another cool idea, when you resize the window using the triangle corner, it should be able to "snap" onto the screen border or another window. I haven't seen that idea done on any other OS.
Now that you have cool shadows, maybe you can take the MacOS approach to boarders.... i.e. don't have any borders; use the shadows as the borders for the windows. It look's good, and actually save's some screen space. Maybe two different themes, one with the border running along the left and right and another without it?
i've mentioned this elsewhere (maybe in that thread that got closed) but i also like the MacOS idea of maximizing, i.e. it only maximizes the window to the space it needs... again this is a cool space saving feature and saves you effort from having to manually size the window to it's contents. (Useful for web developers with multiple windows).
One last thing... Please, please, please, let's get some color in the theme. I see grey, on grey, on grey, on grey....
