I’d be very happy for an option to customize the “Author” field when in library view/display.
Last name + Initials only (Doe JP), or Full name (Doe, John Paul)
Ability to remove comma and punctuation “Doe JP” instead of “Joe, J.P.”
Ability to either display
a) First author last name + et al. “Doe et al.”
b) First author last name + initials + et al. “Doe JP et al.”
c) A fixed number of authors (e.g. 2 authors + et al.)
d) All authors
The main reason being less cluttering (punctuations and commas) and space use - i.e. how wide the author field needs to be.
