Doesn't appear to work.

Doesn't work since at least May 2020. Tracking issue (still open): https://github.com/noam3127/github-code-folding/issues/1

Very useful addon. But there is one bug - I cannot fold the last element of anything.

Do what it is intended to do. Nice job :)

If I could ask for one improvement, I'd say I would like to keep the blank line between two functions (the folding of the function on the top also fold the blank line in between and it reduces readability imo). Thank you anyway.
