Yes, very handy little plugin. But! Too few options of screen width...

Cool but not enough !
Will you add some settings options ?
4 sizes, It's not much. Thanks for dev

Why can't I add more screen dimensions?

I would like to be able specify any width and height sizes as well as window position!

Adjusts the width to whatever you want, although I would love to be able to adjust the height also, otherwise this would be a 5 star rating.
