@bigdutch, that is correct. Just try it because you won't break anything

@sebkun: 1) jReviews is developed using a its own framework, so Joomla standards were thrown out the door from the start. 2) This isn't a simple theme override, this is a complete override capability which allows you to override ANY file. I think it's better to keep all modified files, theme and php in the same place.
