I wonder if there is a way to make the backend look as i want. so which one is the css for the admin space? and how can i delete this "comments" tag in the main navigation, unless i don´t need comments / or i don´t have them....

Why do you want to modify the admin backend? This is not recommended and you would have to do it all over again with every update.

You can do it if you like of course, but you are completly on your own on that. The css is `zp-core/admin.css` (you guessed it, don't you?..:-))) and the main navigation tabs are printed by `printTabs()`on admin-functions.php.

Cool, thanx. I knew it! ;-)))
