[Feature Request] Write characters with mouse

Hi,
I’m interested in learning Japanese, Mandarin and Arabic. I think it’s extremely important to practice writing characters in new alphabets to properly remember them.
I’d appreciate it if Memrise had a feature that asks you to draw the characters with a mouse or even to write entire words like that.
I know one could use a pen and paper and practice it themselves, but that’s cluttery and inconvenient.
