Multiple-Display Power Tools For Linux?

shift writes "I've used multiple monitors for years (currently 3) and find that Linux is lacking in power tools for such setups. Even Windows 7 has added the feature to move a window from screen to screen with keyboard shortcuts. Are any of the major desktop environments adding such features? I'm still stuck on FVWM and have defined functions to swap the contents of screens as well as move windows from screen to screen and so on. But this just seems like such basic functionality people would want in multi-screen setups that I'm surprised I don't find any of these features in our latest desktop environments."
