If your desktop deteriorates into a morass of windows, look to Mosaico to help you tile them neatly. You can use this $10 window manager (14-day free trial) to create different desktop snapshots for various situations.
The simple interface revolves around taking snapshots and restoring them. Once you're happy with the way your windows are laid out, click the snapshot button to save the arrangement. You can save up to eight different desktop snapshots, and restore them easily from the program's snapshot browser.
When restoring a snapshot, Mosiaco will open relevant programs if closed, and will minimize others that are not part of the snapshot. It cannot, however, go as far as opening specific documents.
Snapshots aside, Mosaico also comes with an enhanced window-snapping feature which can be accessed by clicking the arrows on the program's interface, or by dragging windows around. The latter can be achieved by enabling the "Arrange manually" option in the toolbar, or by pressing the "M" key. Mosaico supports multiple monitors well, and features a built-in button for moving windows between monitors.
Position previews make it easy to drag windows to an exact position on the screen. Mosaico's main weakness is its current state of Windows 8 compatibility. Although the program runs fine on Windows 8, there are some small quirks such as random display issues, inability to set custom keyboard shortcuts, etc. These issues do not occur on every Windows 8 system, and will be fixed in the program's next update.
Note: The Download button will download the software to your system.

"The Two and the Heart," courtesy Vladstudio.At first glance, Danijel Krolo's "Be My Valentine" appears to have a hard edge, but look closer and you'll find a soft heart. This wallpaper would make a great tattoo. Vlad Gerasimov's "The Two and the Heart" (shown here) has a deceptively childlike appeal, but the color choices reveal a sophisticated palette. Michelle Fazekas's "Valentine's Day" is simply beautiful, with its toned-background and delicate, almost lacy graphic heart.
