Operation visibility

[krshackleton]

I have trouble on my phone distinguishing "+" from "÷". I see 2 solutions: to have the option of using "/" instead, or maybe another character set might fix the problem.

I already switched the Font to avoid these issues, but to be honest, this did not solve this issue.

@HarmfulBreeze Do you have an idea despite just going back to the "" char? I would love to avoid this step, but the current state is not quite good. I though about using a (decent) color variant to distinguish both operators, but this is not intuitive, I guess.

I actually think giving a color to every operator is a good idea, it's good for both accessibility and readability :)

I will try if my design fellow in my head would react with consensus.
