As of version 3.3.20, when you open the dropdown to choose an event to bind to a Scrivener scene, you are limited to a title-only search.
However, almost everywhere else there is a dropdown for choosing something, you can also input the id of the item for faster retrieval.
In fiction writing, for example, you have tons of events sporting the name of a character. It becomes tedious to find the event you are looking for.
