I apppreciate that Microsoft is looking at this, but they don't seem to be aware of most other window managers. They've identified "problems" that others have long since solved. For example, Microsoft finds that maximize isn't good on large monitors and wants a way to zoom less in one direction. They also want this to be possible with minimal mouse precision. If you look at Window Maker on Linux, a single feature solves both of these problems: you zoom by double-clicking the title bar with modifier keys. So what you're clicking is big (minimal mouse precision), and you have 3 options: Shift for horizontal, Control for vertical, or logically Shift+Control for both. And if you look at a Mac, while Cocoa's default is to zoom full-screen, apps are encouraged to define an "optimal" size for content that can be quickly toggled (between the user's last custom size/position, and the optimal one). This is literally one click to make the window look exactly right.
