I was wondering if there was a feature in DisplayFusion that would let me define areas on my monitor that when I dragged windows into them, they would snap to a certain size. Like, if I had an area in the bottom left and dragged a window there, I would want it to snap to 1/3 of my monitor width.

Kind of. The main thing I want is to be able to define the size that the windows gets snapped into. I recently got a pretty large monitor and the default windows 1/4 or 1/2 snapping isn't that useful. I would much rather have a 1/3 and 2/3 option.

So, I would like to be able to say something like: When a window is dragged into the top left corner(or a predefined area of the screen), then increase the window size to 1/3 of the monitor width and snap to the left side. OR When a window is dragged into the top right corner, then increase the window size to 2/3 and snap to the right side of the screen.
