WHAT DO YOU RECOMMEND
A simple option to choose whether a code block will have line numbers or not.
HOW COULD IT BE DONE
Up to developers to decide, seems pretty standard solution, design-wise.
REAL WORLD USE CASES
I find it very hard to refer to code parts when doing some code explanations and such. It would be nice to have a code block with the code and line numbers so I can refer to line numbers in paragraphs below.
