Yes, please! I got Doodly specifically to walk my online students through Punnett squares and I had to use an asterisk to indicate the color-blind allele and just had to use an image for 2 to the nth power.
The minimum we need is superscripts for powers, but additionally a fraction tool as well. With decent maths support, Doodly could become a major player in producing online/video tutorials for maths and science. Just get on with it.
