Windows 7 introduced great window management keyboard shortcuts. Pressing (and holding) the Windows key and then tapping the arrow keys allows the window to quickly be maximised, restored and docked to the left/right half of the screen.
One of the first things I missed when I started to use Ubuntu was this window management. After some trial and error, trying out different Compiz plugins, I managed to simulate the Windows experience.
The Compiz plugins I use are "place" and "grid". These are the settings for grid. Hopefully I won't have too much trouble getting it to work again when I inevitably lose my configuration after updating Ubuntu some day.
