I've just added all of my own hacks I had for the perl version by only editing the templates. The templates have been long awaited but it has certainly been worth the wait, it will be so much easier to upgrade, new hacks are also easy to add, not to mention how easy it is to change the appearence. =]
Only thing I've been annoyed with is that PHP has to be written inside SSI-comments instead of normal PHP-tags. Why is this?
