On Mac I sue my own customised version of Markdown using CSS as a linked style sheet. Hoewever under IOS I have no idea how to implement this.
Further, it would be beneficial for new users to Markdown to have a kind of reference either on keyboard or using a shortcut to get into it and makes it easier for them to use it.
Underlining is not part of the MultiMarkdown spec. We do not support non-standard features as there are too many flavors of Markdown out there. MultiMarkdown is generally considered the next extension of Gruber’s original work. If Fletcher added features to MultiMarkdown, then they should be available in DEVONthink too.
I second the request for support for CSS customization on iOS. Pointing to an external stylesheet on a web server works, but pointing to a database item does not. Since links to images in DTTG are supported, I’m surprised links to CSS stored in DTTG don’t work. It’s perfectly standard MultiMarkdown.
The download contains the markdown file for DTPO or DTTG and the correlating CSS style document. The text is in German but should not be an issue as it goes more about the functions than the content.
