The monitor splitting hooks can't currently hook the Windows Aero Split functionality, but we do have that open on our list. We'll be sure to let you know if we're able to implement it in the future.
Thanks!
Is there any update on this? I really want this feature. One of my biggest reasons for using Display Fusion... Monitor Splitting and the ability to quickly maximize a window into a given virtual display. When I maximize any native windows app like Explorer, it ignores the splits and maximizes it against the entire physical display.
