I have another plugin which inserts itself above this one because the default hook priority for YARPP is 1200. I have changed it manually to 9 "add_filter('the_content','yarpp_default',9);" But, of course, when the plugin is updated again, I will have to change it manually again.
I would love it if you could add a filer hook priority dialogue that would allow users to change that in the admin section for the plugin. That way the position of the plugin content remains constant even after the plugin updates.
Cheers.
