on the blue one that drop down when you click, you should make the cursor look like its a link almost.
Code:
a.navhead2 {
cursor:pointer;
}
pretty good stuff if that was ur first go ever with the jquery

.
i prefered version 1 to version 2, looks uneven with the arrows hidden
ah also if you go crazy with the mouse it just ques the animation. to stop that add a .stop() just infront of the .slideUp() etc
