[Feature request] Add copy button for website section link

# Feature request
Every now and then I link a MS docs page, and it would be super useful if I could click a section (or a button behind it) to copy a link to the section, rather than to the whole page. For example on https://methodscript.com/docs/3.3.4/Advanced_Guide.html, I'd like to be able to link the recompile section directly (this even works https://methodscript.com/docs/3.3.4/Advanced_Guide.html#recompile), but there's no button to copy to get that link directly.
