Chat feature for Doodling, like nintendo DS chat rooms.

A lot of fun doodles and chats were done back in the day on the nintendo DS with its unique chat interface, I think it would be a nice little feature for Discord to implement. It would be interesting to see how creative people could be in, for example, doodle only chat rooms on Discord servers. This could be done via a seperate tool like MS paint, but if it was baked into Discord we would see it used a lot more often.
