Not a problem, and thanks for being open to adding it! That would really help so it doesn’t break when we update the plugin in wordpress. I guess i thought it would have just taken the list of supplied options and then transformed them and passed them to get_posts(), not pull them into a pre-defined array.
how I am using this:
[tpg_get_posts fields="post_title" author="-270" ]
to exclude an authors posts
