Feature request: Table of contents in exported PDF

[HanEmile]

Describe the feature you'd like
Exporting a book as a PDF containing a Table of contents (not on the first page, but embedded in the pdf file so that PDF viewers can use that information accordingly)

Describe the benefits this feature would bring to BookStack users
The benefit of this would be that books could be exported and used in a way that doesn't include having to tediously search for content in the PDF that is structured in the book.
The structure from inside bookstack could be contained in the PDF.

Additional context
Here a screenshot of how firefox displays embedded table of contents:

Hi @HanEmile,
Such as table of contents is not supported by the default PDF converted in BookStack (DomPDF).

BookStack can be configured to use WKHTMLtoPDF instead for PDF conversion as described here:
https://www.bookstackapp.com/docs/admin/pdf-rendering/

Unfortunately in the most recent (and popular) version, 0.12.5, table of contents functionality does not seem to work as per this issue:
wkhtmltopdf/wkhtmltopdf#3953

The workarounds from that issue, of using a development build from here did seem to work for me, producing a PDF with the embedded TOC.

A release candidate for the 0.12.6 release is now available for download, which should contain changes which possibly address this issue.

Would appreciate downloading the package and reporting back if any issues are encountered during testing. Assuming all goes well, I plan to release 0.12.6 on the 2-year anniversary of the previous release i.e. June 11, 2020.

Hi @ashkulz,
Sorry, I had missed your message before, Just coming across this now.

Just want to say, thank you so much for your work on wkhtmltopdf; the expertise and effort you spend on that project is greatly appreciated!

I just ran a quick test on 0.12.6 and all seemed to work perfectly. Thanks!

Since a workaround for this issue now exists, by using the wkhtmltopdf option, I'll therefore close this off.
