Sorry, the forum cleaned out any posts without a response for a few months. I don't have any plans to incorporate this feature exactly, but you can do something about it using version 3.1.6. Create a custom HotKey and have it change the size to a specific pixel value, not a percent. Use the value of your 2 monitor widths combined and have the DF hotkey also move it to the top-left corner of the monitor. In version 3.2 you will also be able to specify which monitor number to move a window to.
