Mac OS X - Quickly hide all windows except for that one you need on your desktop.
I'm regularly having this problem:
I've got plenty of finder/application windows opened and suddenly I need to grab a file from the desktop and drag it inside one of my finder windows.
Normally to do that I'd need to manually minimize all active windows leaving on the desktop just this one finder window I want to drag my file to. This is very cumbersome, so I came up with the new interaction pattern involving expose's hot corners.
Idea is to grab this particular window you want solely on your desktop, drag it to this hot expose corner, which shows the desktop, then place your window on the desktop where you want it and then drag your file inside it.
It works like that:
A) click and hold the window you want solely on your desktop, drag it to the bottom right hot corner (by default in MacOSX bottom right corner shows the desktop and hides active windows).
B) with all windows now hidden and desktop at your disposal, place your window where convenient
C) now you have only that window over your desktop and you can easily drag your file of choice inside your window.
Easy!
