MaxTo lets you work differently with your windows, but you have to learn our terminology first.
MaxTo originated as a simple way to intercept whenever a window in the system was maximized, and putting that window into a predefined region instead of the entire screen. It has since added quite a few different features, but this core remains.
A region is a rectangular area of the screen.
This lets you very quickly line up your windows the way you want them. And it doesn't waste a single pixel of screen space.
When you install MaxTo you divide the working area of your monitors into regions. These active regions define where your windows will go.
Your first regions
When MaxTo first starts, and you've walked through the welcome screen, you'll be presented with a screen that looks something like this.
This is where you set up your regions. In total, your regions cover the entire working area of the monitor, there are no gaps.
Each region has its size dimensions in the middle. Above there are two buttons that let you split that region into two, either horizontally or vertically.
You can also join regions into one; click the eraser button to remove the line between two regions and join them.
It can be difficult to know what layout will work for you, so to get a feeling for how you will use MaxTo, simply set up your active regions in the manner you think is best. You can always go back and change it later.
