Making multiple level editor views


I am attempting to create mutliple level editor viewports that are streaming multiple seperate levels, through my time searching through the source code I have realized that a lot of the code written assuming that there is only 1 viewport (modes module, content browser, world outliner, etc.) but does anyone know how it is easily possible to create more than 1 viewport that can stream multiple levels or what the consequences would be if I attempted to make the change my self.

Thanks for any advice.

Try split screen. You can do side by side, or split horizontal.
