Is there any program or way to make Mac OS X's ⌘Tab(Command-Tab) behave like Windows' AltTab?
That is, instead of switching between applications, to switch between windows of all applications?
I do know there's a way to switch between windows of the same application using ⌘`, but that's not what I want either.
I'm not just trying to make Mac OS X behave like my recent former OS, I've been a Mac user for over two years and before that Ubuntu. After using Expose and ⌘Tab I think Windows' or Ubuntu's AltTab is better.

switch between applications using Cmd-tab, but hold the Cmd key after you released the tab key, and while still holding the Cmd key, press up- or down arrow. This brings up Expose right from program switching.
