OSXilla Junk Mail Icon in Mail & Newsgroups

Well, I finally realized that OSXilla wasn't Multizilla for OSX and 
installed it the other day and am pretty happy with it (previously an 
Orbit Retro fanatic)  One thing that's been driving me nuts though is 
that there's no Junk Mail status indicator.  Are there any pointers to 
how to make your own Theme, maybe I'll just pull those icons out of 
another theme and stick em in my own custom OSXilla.  Other than the 
Junk Mail icons it's a very nice clean Theme.
