> It all makes me wonder why both Windows and OSX are so unwilling to either explore more powerful window management, or at least provide APIs to enable power users to build their own. Take a look around at the desktops of the majority of windows and osx users. Not the power users, who are a small minority of the user base of both OS'es, but the "I merely _use_ a computer to do task _X_" type users. Once you start to look, you'll notice a trend. An overwhelming majority of them will be running every single application on their desktop in window maximized mode. And this will be true no matter the size of any monitors they have attached. The closest they get to "window management" is to poke the icon in their toolbar/dock for whatever it is next that they want to see on their screen. Both OS'es likely do have API's to allow for an 'always on top' setting, but with a userbase that is 99% "run everything full screen" at the outset there is no room for those users to make use of an 'always on top' window (because it too would be maximized, defeating the usefulness of the 'on top' setting). Therefore neither maker likely sees much value in exposing those API's.
