Thanks for all your help, but I still don't get it.
I'd like to have my workspace set up like Springheel in his mapper's workshop, but it doesn't work. I can't move the windows the way I like. The XY window isn't even scalable and it doesn't have a title bar.
Fortunately I have a setup with 3 monitors, so now I have the ortho windows on the middle one, the camera window on the left and the properties window on the right one. But this is cumbersome, it involves turning my head constantly and moving the mouse around for long distances.
How can I make the Springheel layout work?
Thanks in advance.
