Spectacle

This time I will share again an application for Mac users that is used for resizing windows.

Spectacle, a free app that is simple and will help you in controling window and customize keyboard shortcuts for resizing your workspace.

Resizing windows sometimes makes users work more freely with lots of windows being opened simultaneously, this simple application really helps users, unfortunately it's only for Mac users.

Spectacle allows you to organize your windows without using a mouse (Source)
