@jay I know it is kind of counterintuitive, but I have been using the Stacks 4.0 Markdown stack in a site I am building with Platform and I have also tried using BWD’s Scribe stack. My reasoning is that outside of Rapidweaver, I use Markdown almost exclusively to process fairly large amounts of text and style them quickly for use in time critical news sites. Both Markdown stacks behave as expected within Platform (even Scribe’s drop capitals), with the sole exception of the various headers (#, ##, etc.), which simply don’t do anything.
So, is it possible to fully enable these Markdown stacks within Platform?
