So I did some thinking and the ignore function isn't worth keeping if it means I can't share what I've made with other people. In this version, I've taken it out. I'm splitting off the ignore feature back into it's own script, which is coming later.
Without the ignore function, this version is a little lean. In fact, it's only a moderator flag. BUT that moderator flag is now bigger and in color! Behold!
