Are there any settings for this plugin?
Nope. No settings page is created. Just activate and start using. No configuration required.
I don't see any of the nice transitions when the toolbar hides or shows. Why not?
You most likely have a lousy browser, like Internet Explorer. This plugin uses nice CSS3 transitions that are supported in modern browsers, like Chrome, Firefox, and Safari.
I have the latest version of Internet Explorer. Isn't that "modern"?
No. See above.
Why don't you use jQuery UI for transitions instead? Then it would work in all browsers, right?
I could. But it would be wrong.
