I'm trying to get the year and the author in bold for all in-text citations.
Thanks to @moewe I already managed to get my prefered style of the Bibliography and also to print the author in the in-text citation in bold. Now there is missing the last step to get my prefered format style.
I would be very happy if someone had a hint for me. I think it's only one line that is missing but I don't know how to edit the year.
