It's an addon called Litestep which is free btw unlike a lot of other addons to mod windows with.
this is the "layout" i used http://mynimal.deviantart.com/art/case-LS-37760903
which i then proceeded to butcher to basically fit the background color of this wallpaper and my needs.
its a text based addon btw.
niiice, thanks a lot :)
now just need some documentations or a good site, since litestep.net seems a bit outdated hehe.
