I can easily create functions to size a window to the left and right halves of the screen, and also create functions to maximise windows.

However in Win10, if you drag a window to the edge, you can snap it to half of the screen and select another application for the other half. The window now behaves like a maximised window (e.g. smaller titlebars) and you get a special drag bar that controls both.

Can we have the ability to do this from DisplayFusion. The main usecase would be when DF is used to position windows on startup.
