Carriage return / Enter within command

Hiya, this is unfortunately not possible, since linebreaks are not supported.

Hey @Cuddly Cat!

If you don't like the idea of adding a - (dash) or an _ (underscore) at the end of the line because it'd look ugly, and if you don't like the idea of having Nightbot sending multiple messages because you want to send everything at once, you can always use the Braille Pattern Blank: ⠀, it looks like a space, but Twitch doesn't remove them if you type a lot of these, unlike it does for excess of spaces.

That looks pretty promising, looking forward to implement that, thank you very much
