Desired Feature:

I am testing BookStack for a setup where we heavily use https://github.com/hackmdio/codimd for collaborative editing. Bookstack should then make those documents "persisted" and better organized.

CodiMD uses Github-style markdown, so there are currently some differences.

One of that are the callouts. As mentioned in #469 you are able to add callouts in Markdown via <p class="callout info">A success message</p> (or the same with div's). In CodiMD the same thing is achieved with: :::info A success message :::.

I'd love to be able to use callouts with that :::info-syntax instead of the HTML-Tags. I'd suggest making :::info Message ::: behaving exactly as <div class="callout info">Mesage</div> because we also use multi-line callouts where the <p>-Tag would fail.
