Changing windows size and fps at runtime (smoothly)

[Shadowblitz16]

can support for changing window size, position and fps at runtime be fixed to do so instantly instead of taking 2 seconds?

I think it might allow for some cool games. currently this is what I am doing but the app freezes because I am setting the fps every frame..
