Very nice! But please move the webshop-button to the right, about the location where it is on the startpage (but not IN the big content-box but in the line where it is now (under the fourth small content box). Ähm - know what I mean?
The highlight button "home" of course will be the same as the highlight button "contact" (on contact form page), which you gonna make like the "senden"-button...
Then we can take it as your final proposal!
