When using the "New look", it is currently not possible to display a "Yes/No" field asa checkbox in the "New look". The only possibility that exists is the default "Yes" or "No" dropdown. When reverting to the "Old look", the functionality for displaying a "Yes/No" field as a checkbox is implemented.

Generally speaking, the formatting options for a "Yes/No" field is missing in the "New look" and would be nice to have implemented.
