GridMove is the answer to the Acer GridVista.. It’s a window organizing software, it can increase productivity if you know how to use it.

Excerpt

GridMove is a program that aims at making windows management easier. It helps you with this task by defining a visual grid on your desktop, to which you can easily snap windows. This program comes bundled with some predefined grid templates, that can be easily swaped, but also has ways of creating custom grids or sharing grids made by others.

GridMove makes moving windows, resizing windows, displaying them on cascade or on mosaic, making them on top or anything you can think of as easy as drag and drop.

This tool was made taking in mind those who own big screens and keep organizing their windows. This program is specially useful for anyone that keeps more than 1 window on the screen at one time, because it helps the user to maximize the usable space of the monitor, by resizing the windows in a much easier way than moving and resizing them one by one.

Thanks to its simple interaction methods, GridMove becomes intuitive and fast, helping you to improve your workflow.

I really like it. I can easily drag my window to the desired area and automatically it resize according to the specified size. There are some ready made templates for that can be use right away. It is ok for most user, but some power user might want to create their own template (this is where GridVista fail). Just follow the simple instruction on how to create your own template, beginners may have a problem here. Not forgetting that it also support multi monitor.
