Scaling interface on 4K displays.
Will Adobe add 150% interface scaling? For a modern 4K 27-inch display 150% is the best scaling value as workspace is equal then to native 2560x1440px. But Adobe can support only 100 and 200% which both are uncomfortable. 100% is too small and 200% just too big. 150% is perfect, and as some Apps can adopt from default system setting (150% in Windows 10) there is still a lot of bugs like 200% scaled cursors in Photoshop and apps like Adobe Bridge or Camera Raw working only in 100% or 200%.
