@Tanmay If it's for adding a language, I wouldn't bother him with that. He will come here when he can

An idea, for whoevers up for implementing it. Would be nice to have an option to preserve hidden header/footer in the url. Using it a lot these days for testing interpreters for esolangs-in-dev and it'd be nice to share esolang programs without overwhelming the receiver with all the code in the header/footer, and w/o leaving them to figure out to hide it on their own!
