Great multi-tasking app

The app can move the selected app to the left or right taking up half the space of the screen and it can also make the app go full-screen. The app allows customized shortcuts to be set in order to accomplish these tasks.

There is also an icon on the taskbar (upper right corner) that contains these action shortcuts as menu commands. Great little app, highly recommended for Yosemite users.

Please note that for El-Capitan users this app may not be that useful, since the split-screen option is natively built-into the operating system.
