It would be nice if the tool bar in new adobe could be made horizontal or docked to the window above such that it does not cover the document when in a splitscreen view. It may be able to be done but I have not had success in the short time I have tried. Also, being able to have a pen to write/draw on a pdf would be nice, I feel I remember being able to do this in the past but have not been able to in a while.
