When manually entering a citation, the reference type provides many fields which will not be displayed for various bibliographic output styles. Every school I know adopts a single bibliographic output styles throughout its courses, therefore students will rarely switch between styles.
Suggestion: depending on the bibliographic output styles selected, within the reference options, a filter should be added to only display relevant fields for that output style. This will avoid wasted time searching for information to enter into a field that will never be used for that style.
