Hey folks, I've just
a) completely rewritten the Retort frontend to better take advantage of the new widget system (Now I'm not embarrassed about the choices I've made!)
b) added limited emojiset support (giffed below)
There's some detailed instructions on how to get set up with limited emoji sets in the readme as well.
Feel free to pull it down and have a play, and let me know how it works for you. !
I've thrown it up on my test instance, so you can have a play with it there before installing it.
