[Plugin: Profiler] Using ModRewrite to use pretty permalinks

This is a great plugin and does almost exactly what I want.

However, I’d rather it display using pretty links than with the query string. I’ve been playing around with ModRewrite and my .htaccess file. I’ve tried various permutations of this but none of them have worked:

RewriteEngine On
RewriteRule ^commenter/([^/]*)$ /commenter/?user=$1 [L]

I think my problem might be that I’m stepping on the WordPress ModRewrite rules somewhere with that, but I’m not sure. Any help would be greatly appreciated.
