Feature request for configuration of hiding the scroll bar button

[leozzyzheng]

I need config the toc for my markdown files to generate the correct toc in html. But I notice that I can't hide the <a id="sidebar-toc-btn">≡</a> by config, the button will make the pdf also contains the button image.

Now I need replace the <a id="sidebar-toc-btn">≡</a> to none after generated the html files from markdown, so it would be much appreciated if there is a config could do that.
