It's interesting that most OS X users don't easily recognize lower as being the specific feature that's being sought. If I have a window blocking most of the screen:
- I don't want to disturb its position, so move is useless.
- it's blocking several windows I want to see, so switching to the all-window view and picking one doesn't help much
- I still want to see part of the window, so minimizing it isn't helpful.
I want to lower it to be behind the other windows. In Unix/Linux, I can just keep typing at the parts of it I can see while leaving it in the back. I just leave the interesting parts of windows visible and interact with all of them without destroying how they're arranged. So easy.
OS X allegedly doesn't even support writing code for pushing a window to the back. Nor typing and mousing at partially hidden windows without using modifiers. Nor is it even remotely decent at leaving my windows where I left them through sleep, being moved, etc. If i kill a window, OS X raises a random number of other windows of the same type, forcing effort to restore order (there may be a setting for this, I'm looking). If i open a window from a window on one screen, the new window will appear on a screen chosen apparently at random instead of on the one the initiator window was on (also might have a strong, not sure).
Overall, OS X window management is abysmal compared to the *mix world - highly frustrating after working with the real thing
