Hi, I've tried out the window snapping feature of DisplayFusion and it works fine in some situations but I think it could be even better. I'm used to WindowSpace from ntwind and that provides different snapping (it snaps as you move the window, instead of after you drop the window) plus it works with MDI windows (snapping them within the owning application's main window). The bottom line is that it's much easier to get the result that you want.
