No search function on your website :(

hello, please clarify what theme are you talking about :) thanks

I am not referring to a theme. I'm looking on your own aitthemes.com website for a new theme. I already own Fullscreen and am looking for a new theme for a site I wish to redesign. So I wanted to search your themes for specific features, but cannot see a way to do that? 

I see, what specific features do you mean?

I'm looking for a theme with a larger (tall) header and with either a kwicks or slidedeck style slider.
