This is unacceptable by any standard. When a passage from a resource is highlighted, copied, and pasted in Notes, there are no citation details included. How is that possible? I can understand wanting to turn that off in certain situations, but the default OUGHT to be to include such details, because of a little thing called plagiarism and a user's need to avoid it. Oh, btw, this USED TO BE the default, so once again, a once useful and essentially necessary function has been dropped from the program. Is it deliberate?? An oversight?
Perhaps the ability to turn this on is available somewhere in the program, but I haven't found it, so if it is available, then its hiddenness is a bug all its own.
