The current UI supports h2, h3, h4 through the drop-down menu in editor (see first attachment)
And when configuring the TOC in Settings (see second attachment).
Could you guys add h5 support? Since h1 is apparently reserved for something else (article title?), we currently have only 3 levels of fully-supported headers. Today, I encountered an article which needed four levels.
In addition, when I manually insert the <h5> in the HTML editor, the font is barely discernable from regular text.
(See third attachment).
Could you add an underline, italics, or something else to differentiate it from both regular text and h4?
