Hi ... first of all thanks for trying out the plugin and for getting in touch. I've been wrapped up in my day job for a while so I haven't had the chance to catch up with the forums here.
I'll add support for this into the next version of the plugin to avoid the need to hack
functions.php; I've been working on my day job as well as getting a new version of the plugin into a shape fit for release but I hope to be able to do this over the next week or so.
Once again, thanks for using the plugin and thanks for getting in touch.
