So Windows' default window manager resizing has one thing I miss in AltSnap. When I start to resize a window, and I want to cancel the resize, I'd press ESC, and that would revert the current dimensions to the initial dimensions (right before resizing). Pressing ESC while resizing in AltSnap is equivalent to just letting go of the activation key. Ideally I'd want an option in the ini file to swap this behavior.
