The submissions forms have not changed much. The only thing you can notice is an extra button next to the input fields for the author names. Next to the Add button, which is common for all repeatable fields, there is the Lookup & Add button.
It's by clicking on that button that the Look-up User Interface appears. If an author name was filled in but not added yet, the Lookup User Interface will immediately perform a search for that name. Otherwise the search field remains empty and a list of known authors is displayed. The list of authors is updated as you type in the search box.

Clicking the Lookup button brings back the Lookup User Interface. This works just the same way as in the submission forms.
