Better responsive menu

I would like to request a better, cleaner responsive menu. How the menu is currently set up it simply acts as any normal text group which bumps text down to the next line, which makes the top of the page on mobile phones very cluttered. There are also gaps that are created depending on what words are in the menu itself. This reduces the amount of actual page content that can be seen and gives off less of a professional feel.

Is there way that you can update the mobile menu so that it is more of a drop down similar to BlueMasters or Phoenix Responsive Theme?

Corporate Clean is a great theme and having a truly responsive menu is the only thing that would put it over the top.

In the meantime is there a fairly simple way to create a better mobile menu. I have no problems with how the menu looks on the computer, simply looking for a mobile only solution.

Thanks in advance.
