Windows Layout Manager: Your Desktop Across Multiple Screens
Windows Layout Manager lets you position and scale multiple windows on multiple monitors easily.
To install it, just unpack the contents of the ZIP file to a folder of your choice.
The main application has a basic window that allows the management of various layouts. Adding new ones, editing existing ones, configuring the options, all the basic things you can expect from any normal application. When closed or minimized it sits in the tray and offers a tray icon with quick access to layouts that are enabled (it’s possible to exclude layouts from populating the tray menu since some layouts are not meant to be applied directly)
