Here's a simple feature that would be nice to have:
<p>
On the bottom of the results page, have a link to each 
page of results (maybe up to 10 pages linked per page, 
like google), the starting point, and the end point. 
Alternatively, a drop box of results pages, or the 
ability to list as many results per page as you like.
<p>
I'm going to build a webpage with this script soon, 
and I'd be happy to implement it myself as well.
<p>
I'm personally going to build in the ability to 
generate a PDF of the results, which will be helpful 
for me. It might be too much bloat for you to include 
that in your project though.  Good luck, and thanks 
for your hard work.
