Many features

Features:

1. Limiting autocomplete results in field settings
2. User can change LIKE query behaviour: start, end, both
3. Validation: minimum selected terms in settings
4. Autocomplete widget for taxonomy manupulates tids, not names
5. Taxonomy hierarchy support (like hierarchical_select, but simple and handling large vocabularies without overhead)
6. Validate that last term in hierarchy was selected
7. In multiple select mode user can define in field settings which selected term will saved: first, last, or offsets
8. Show term parents option: if only last term saved in hierarchical mode, show parents in widget, but not save them
9. Custom formatters to show term parents in node view if only last term saved
10. Contributed entityreference widget module

But some features are degraded on this moment

1. Ajax cache (not compatible with hierarchical select)
2. Autocreate term
