Also, for the people who might not want you to remix their project, there should maybe be a block that is like this:
set remix to (yes) for everyone
Or like this
set remix to (no) for everyone
But I don't know if everyone would like that. Or if the person won't really care. At least I don't really care about remixing but I don't know if everyone likes that.
P.S. I hope this gets a response or the blocks get made or something! Bye!
