PutAside

PutAside is a tool that lets you hide all the windows you have active on your desktop in just one click.

You can also choose any key shortcut you want, so that by simply clicking a couple of keys you can minimize all of your open windows or, all of them expect one (similar to the typical alt tab).

The application is very small and takes up few resources, so regardless of the computer you find yourself on it should not pose a problem for performance.

PutAside is an interesting application for those who work in an office and who might have to, occasionally, close many windows very quickly.
