A book had chapter heads like

<h1>17</h1>
<h2>Jack<h2>
<h3>Monday</h3>

There is some other formatting between heads that makes it difficult to combine them into a single heading in the text.

Sigil generated a TOC with three levels; I wanted all 3 titles to be combined in the TOC.

Using the plugin, it combined h1 and h2, but simply deleted the h3 text.

So adding at least one more level would be appreciated.

Also, it offers a choice of space, em or en dash and tilde as a separator.
Could add period and colon to those. Or just allow to type in any character.
(I know I can just use the tilde and replace it in the ncx myself.)

So I went back back to using regex to build a "title=" tag in the h1 from the other heads.
