Hi, I’m not sure if this is the right place to post, but I noted that OP had mentioned “callout” as missing within Ghost markdown.
I agree that this is the case. Grav has a neat modification of Markdown which has the ability of adding callouts/alerts within Markdown. This would make is possible to have an entire post in a single markdown card (Although I appreciated that this takes away the flexibility afforded by the awesome Ghost editor.).
This has an added advantage of allowing global footnotes (which is being voted here)
So is it possible to have alerts/callouts within a markdown card instead of them existing on a separate card?
