When using the Post field - it would be good to give the user the option to create a new Post.
Is it possible?
I haven't checked what's possible via building a relationship between two post types - but even if that feature exists within relationships - it would still be essential to have it on the Post field.
Also regarding the relationships - when using the Post field, it's a similar thing. Maybe it would be good to have the options on the Post field to create that relationship - and let the field reside within the desired metabox.
