I was surprised there still isn’t a feature request for question one. I thought I had created one, but it turns out I had only created a help topic: Is there a way to preview entire embedded markdown files without scrollbar?
It looks like another post here I had created with the intention of being a feature request is also resolved help: Embedded .md files in entirety (without scrollbar)
I will create a feature request for sure this time. Here it is: Embeds without scrollbar
Thanks.
