Possible to use only some of the windows?
 

I like the healthbar, group, cure and the bar at bottom of screen, is it even possible to use only those windows?

Yes, it is possible. And u forgot one window, that chat window.
But yes, it is possible, if u right click the window, there should be a "close'' selection, that should close the window.
