For me the properties panel is an "always on" panel to check the correction layers and since it contains the typographic informations too, I could close those panels when I'd get the same informations at the same place. I made a layout to show how much space could be saved by just using the same layout as in the specific panels.
Yes, I could collapse the scections and open them when needed and close them when not... But then I rather keep the specific type panels open and don't use the properties panel for type layers at all. The "quick action buttons" at the end of the panel make more sense in the menu bar?
