New thing that I suggest is the option to make template, for example for journal or book section.
I found that I need templates, when I enter few journal Articles or book sections from the same journal or book.
In this situation I don’t Want to repeat on fields like journal name and journal volume or book name, publisher and other thing.
So if I can make Template that allow me to decide Which fields to enter in the Template, It will help me and I thing also to other users.
