Relational Fields

I have the pro version and just going through the testing of it.

I’m just trying to clarify the difference between the post object, page link and relationship fields. From what I can see having tested them they all pull in posts that you allow when setting up the field and you can have various settings etc for each but I can’t disseminate a significant difference between them.

Am I right in assuming that there is very little difference between page link and post object but the relationship field gives you a few more options like minimum and maximum posts?
I guess that the principle of what you can show on the front end for each of these 3 fields is once more almost the same for each one and obviously limited only by the php and css you develop?

Sorry for dumb questions I just can’t see much difference between them, anything I’ve missed please let me know.

Thanks and great plugin, top work.
