Tiler sits in your notification area and with a click of a button, lets you tile the active windows on your desktop. This can greatly enhance your productivity when you are working with multiple windows.
You can tile your open windows either horizontally or vertically. Tiler is a cool tool which can enhance your productivity and make you work better and faster. Windows XP users may find this app particularly useful!
