I do this now usually I have it labeled either page group, or category. If it's a larger site I'll assign colors and the sub-pages follow the color scheme. Currently doing that by adding a blank section. It would be nice to be able to change page title colors across the board to follow color scheme or if it auto generates to follow a color hierarchy. ( It would be awesome if "categories" were assigned a color, let's say blue-400, all sub page titles were assigned blue-200) Or being able to manually choose your colors and just assign your own color system.
