Seems like many are already asking, but this feature isn't anything special where you need to use Ivory. All we are doing is showing the post you are linking to visually vs just having a link to a Mastodon post which anyone has been able to do since the beginning of the service.
That and making the process of copying a link to a post and pasting it in the compose view more automated.
