Many users are not going to be aware what attributes are even available for a post, let alone their specific names and paths. Even though I know how to view that information, it's not entirely clear to me whether what I'm entering is correct. It would be beneficial, then, to offer more built-in options for this filter type beyond "text" and "embed.external.uri".

One thing I'd like to be able to do is pull in posts that all share the same root. When I look at a post in developer tools I can see that the full path is something like post.record.reply.root.uri. When entering this in the attribute comparison I am just doing record.reply.root.uri but that doesn't seem to be working. It's not clear to me whether I'm just entering this wrong or if the record attributes aren't available at all.
