I've just released
WindowSizer , an application designed to help you view multiple application windows at once. Set up a tiled arrangement of your choice and double-click the WindowSizer icon to snap window edges to each other or the screen's edge. Resizing one window resizes the others for a no gap, no overlap efficient workspace. Swap window positions in arrangement with drag and drop. Save common work arrangements (including Internet Explorer locations and Explorer paths) to bring back later.
For people who commonly compare data in two or more different windows this is a useful app. With bigger monitors and higher resolutions these days more people want to view multiple application windows at once. WindowSizer make this efficient. Let me know your thoughts and suggestions.
