Feature suggestion

I like how this integrates with the built-in site search, however, I would like to suggest a couple of changes to the plugin:

1. Add a Submit button to allow site users to submit their search. As it stands, I find I have to select my categories, then place my cursor in the field for the search term and press the Enter key on the keyboard to start my search
2. Include a method for the site admin to customize the order of the categories. This is less important than the first, but a definite nice-to-have feature.

Thanks for putting this together!
