WordPress Post to SMF – what would make this plugin much more useful

Otherwise great plugin – but what would make it much more useful is to be able to choose which WP posts get posted to the SMF forum. As it stands now, EVERY post goes into the forum. I’d like to either be able to pick which posts get posted (by ticking a box) or basing which posts are posted by their category. (in other words, only posts from category 1 will be posted to the SMF forum.)

Thanks!
