I tested this plugin with Nathans plugin and I couldn't find any errors, so I would assume that both plugins are working side by side without any conflict. Both internal and external links are rich embedded (except internal links that are pointing e.g. to /forums or /calendar, but this is normal. Only records are embedded).
@A Zayed I have some small question though:
After embedding external links the embedded content is editable. My suggestion would be, if possible, to prevent editing so users or mods do not accidentally alter the embedding. This happens only after embedding, saving and editing the post again
Are only those images pulled by the plugin that are marked as meta or og-image? I tested with a site with a lot of images and only the title and text is pulled (I checked to pull every available information)
Is it a wanted behaviour that we cannot move the embedded content like the default ones (e.g. quotes or videos with the little movement indicator in the top left corner). Same as above, only after saving and editing the post again
Cheers,
Phil
