I am now using a 4K monitor, and by default the Key Editor opens in the Lower Zone, however while convenient, I had to change back to using the Key Editor, in a window due to the lack of a Visibility Inspector.
Could Steinberg please look at this, area of the application since the default preference is to open Editors in the Lower Zone, and one of the most amazing features ever made by a DAW and software company, is nowhere to be seen.
