Multi-Universe Plugin Working! but one problem...

i know it seems like i am always just ask for help, and i am sorry for that.

Anyway the Multi-Universe Plugin is working, i am just wondering how do i edit the different backgrounds to the big space where every sub system is displayed isn't black and says Hazard.

I want something more relevant.

well you know how in crossfire the main universe is called Universe.
in default multi-universe its called Hazard (dunno why.)

Don't tell me how though
