I'm writing a plugin that adds some extra thumbnails, checkboxes, etc to the end of a post.
I'm trying to figure out how to use add_filter properly.
Basically, I've got
And there is a corresponding do_some_magic_at_the_end function that takes $content and appends some stuff to it.
I want this filter to be added after all other filters. I don't want it overwriting any other filter. The docs says default priority is 10, so I assume it is simply being added to a chain of filters that get run on the_content.
If I set the priority to 1, will it overwrite any core functions?
