not really a huge deal, but i think it would be a nice polish on the website to use client side script to allow some sorting of tabulated result data.
not only is it faster and more enjoyable for the user, but it would also reduce load on your webserver and database. and since your already set up and coded to allow server side sorting, making this all fail gracefully for non js enables users would be cake.
heres an example:

Nah, it's a valid suggestion =) I've wanted to play around with js sorted tables, but tbh, I've just been too busy with other stuff to check it out yet. Someday though, someday!
