I'm used to recently using both Moho and Clip Studio Paint, and they both appear to pack a lot more onto the screen at 1920x1080. CA5, in comparison, seems to fit a small percentage of the amount in the same screen. I've included screen shots of both Clip studio and CA5 as a comparison. I also note that in CA5, I cannot unselect the tick box under "Edit->Preferences->Interface->Enlarge Font and UI"
