Hi, and thanks a lot for your wonderful module. I found it even simpler than the ones that were available for Drupal 6.

One small thing that could improve its usability IMHO is creating a new type of views "Display type". As long as node reference fields may call only the views with de display type "Reference" I think it would be a good idea on your module that once the user wants to set the field formatter to the views type instead of listing the whoooole list of views it would just display the ones of, let's say, "formatter" type. That way, when creating a views for using as formatter we should select "Formatter" as "display type". I got some sites with a huge list of views and that would be a plus ;-)

I've just tried to provide some feedback :-) Thanks again.
