First up, thanks very much for all the work you've put into this - it's an excellent piece of software, particularly for those keen to keep all the data together 'offline' to save repeat scrapes in future, and compliments XBMC very well.
XBMC supports local actor thumbnails in a ".actor" folder (forum.xbmc.org/showthread.php?t=56287) per movie - are there any plans for support of this in future? I've been using the single actors folder currently in use with media companion, but this seems like a great step towards being able to keep everything together (there's certainly some duplication, but for the size of the actor images it's worth it, imo - it also allows for future support of 'per movie/show' actor images, as currently used by tvdb). It also solves the actor image location issues that seems to cause problems within the nfo files - there's no static paths this way, reducing problems when things invariably get moved.
