TBH I don't like that we're sending potentially large json string to the server as a query parameter. Any better ideas for that?

This is very cool and reminds me of #662, which i had attempted to implement at some point and stopped. Let me think about if that is applicable here, maybe this idea of generating links should be more extensible somehow...
