A generic entity reference field
Four widgets:
- Two implemented on top of the Options module (Select and Radios/Checkboxes),
- Two autocomplete widgets (one with one text field per entry, one tag-style with comma-separated entries in the same text field)
Two formatters:
- A "Label" formatter, with optional link that displays the label of the referenced entity (the node title, the user name, etc.)
- A "Rendered entity" formatter, that renders the references entity using a configurable view mode
Integration with Views (for both forward and backward references)
Integration with Entity Metadata (and as a consequence with Search API and the like)
Integration with Devel generate
Integration with Feeds and Migrate (>= 2.3) for painless data import
