The new interface, with its inability to open multiple references simultaneously, is a severe disadvantage. This is an unwanted and severe limitation in the capabilities that were in Endnote 9 and previous versions. Taking it out makes no sense. Now I can’t compare notes in 2 or more references, I can’t (easily) copy and paste between them, compare author lists, and many other functions. It’s enough to send me back to Endnote 9.
Seriously, please put this functionality back in.
