BTW: "direct" embed refers to inserting actual content instead of using an iframe. I've reverse-engineered the original styling of the Mastodon statuses ("toots"), thus the styling is not perfect, but a) the LESS file from which the CSS is derived is being supplid as well and b) there is a filter hook so you may roll your own CSS, too.

I'm going to add this to the plugin documentation as soon as possible, too.
