Add Search Box to Page Menu

Hey Flynn, thanks for all the work you've put into this theme! Just registered today and I'll be donating shortly.

My first question has to do with adding the Search box within the Page Menu bar. How hard is that to do?

It would look similar to the designs below


2nd question: I like the layout and look of the Page Menu Bars shown above. If I were to purchase them how replace the existing Page Menu Bars with the new design?

Thanks in advance....vinnie
