A real library is that which I have been asking for since before V12.What do you mean by 'real library'?
Are you looking for additional categories of pre-provided content, or some changes/additions to functionality?
Minimally it is a place where one can store parts that are read only so they can not be changed by accident.
This is a standard feature in every other professional CAD that I have ever used.
Its lack in AD is the reason that none of the companies I have worked for have ever considered AD for their CAD needs.
