Best app to switch between all open windows (alternatives to Witch)
On Windows and Linux one can switch between open windows by pressing Alt+Tab. On the Mac pressing Cmd+Tab only lets one switch between windows of different applications. In order to switch between windows of the same application one has to press Cmd+` instead. Is it possible to disable that behavior, and use Cmd+Tab to switch between all windows regardless of whether they belong to the same application?
