Windownaut is versatile window management app that let's you define keyboard shortcuts and active areas on your screen to resize an position the windows on your desktop.

ZMover helps you manage your desktop layout by enabling you to set the size, position and layering of application windows. Instead of wasting time rearranging windows across your single or multiple monitor display, you can configure ZMover to do the job for you. Simply tell ZMover which windows you want to modify and how, then hide the program and let it work in the background. ZMover will monitor the desktop and automatically reposition, resize, or even keep selected windows below or above the others when they open. ZMover lets you manage windows across several monitors with ease. The number of applications lacking multiple monitor support and the increased desktop space offered by such setups make it more difficult to maintain an optimal desktop layout. ZMover eliminates these difficulties with its ability to define window layouts for different monitor configurations. ZMover features a toolbox with an intuitive view of your display and commands to easily rearrange windows on any monitor. You can also save your desktop icon positions on each monitor configuration and restore them later if they get shuffled. Hot key support is provided to perform operations at the touch of a key, even when ZMover is hidden, including the ability to send the cursor to any monitor. ZMover stores user preferences in a small portable file. So it’s easy to define a desktop layout on one computer and propagate it to other computers in a lab or a data processing center. Organizations can benefit significantly from this capability in situations where it’s important to position windows in a uniform and familiar way across many workstations. If you need to have your desktop arranged in a certain way, stop doing it manually and let ZMover take care of it for you! »

Ever try to size a window so it just touches the edge of the screen? It’s tedious (at least for me). FreeSnap allows you to instantly resize any window edge to the corresponding screen edge. Want that window to touch the right edge of the screen? Press and hold the left “Windows Key” (see illustration below) and press the right arrow. It’s just that simple. The number-pad keys work as well, regardless of the NumLock state.
