@bensu - That would be awesome if you could add the “Copy as HTML” option!
Regarding the 2nd piece: Users can define their own CSS styles that’s stored in “logseq/custom.css” to change the look of elements in LS. So my suggestion was to retain this formatting from the user’s custom.css when the page is exported to HTML, I think it would only make sense to apply this when exporting the page to HTML tho and not for the copy option.
