Ah ah! Perhaps I misunderstood the previous mail.
By "ribbon" did you mean the band going from left to right on the top?
My understanding was for the border around the top box (the one containing "Welcome to blah blah blah....").
I think without the top band it looks a little "empty", but it is just my opinion. Would be good to hear from Slavek and Tim as well :-)

Anyhow, thanks for the big effort so far. No need to rush :-)
