The majority of users have most likely experienced cases when after logging back in or restarting the computer, some of the windows return to their original state, making you resize them manually again and again. With WindowManager, you can save yourself the bother.
The only thing you will have to do to use it is open a new window, set it up in the place and size you want it, and set it from the program window. It's that simple.
WindowManager is a very exciting tool that will save you valuable time.
