Fixed so that you can have multiple floating windows at once
You can have multiple floating windows, but they do not seem to handle as I intend. mousedown seems to interfere with dragstart. Maybe mouseup will work better?
You gotta set the size with px at then end... I also implemented a simple map that will keep track of the windows. Still need much work to be done so that I can open windows as I'd like, and not pollute the global namespace
