Nagamasa...why don't you make the contact search bar transparent, as the contact list??
You can find how to do that here:

You could also add boolvals to make transparent an option...I don't think everyone would like their contacts lists always transparent.
Hmmm...and try also to hide the tabs separators, they look a bit ugly.
Keep up the good work.
