A couple of Microsoft designers working on what was Windows Codenamed “Longhorn” at the time were granted a patent they filed all the way back in 2005. On closer inspection, their idea is reminiscent of the Aero Snap feature in Windows 7 today, but arguably more powerful. The Longhorn designers too thought of this windows management problem and came up with a slightly different solution, which nicknamed to “Aero Link”. The first thing that’s different about “Aero Link” is the way it is triggered. Instead of dragging two arbitrary windows to the sides of the displays, it is suggested that one window be dragged to the titlebar of another, with a visual indicator indicating an action occurring. Alternatively it is also suggested that the same trigger can be performed in the taskbar dragging an application’s button onto another application’s button.
