Illustartion Placeholders
Hi!
I'm trying to implement an initial placeholder page for my application. While reading the HIG an looking at existing applications I found some potential inconsistencies. The HIG says "Illustration placeholders use a colorful graphic for the image, whereas symbolic placeholders use a simple monochrome icon." and "Placeholder pages with the illustration style are primarily used in the main view of an app, when it is empty. The main purpose of doing this is to avoid an awkward empty state when the app is first used.". But apps like Secrets and Fragments use an initial (illustration?) placeholder page which only contains the app icon. Is the app icon also considered a "colorful graphic"? And apps like Loupe and Papers even use a symbolic placeholder page as an initial state. Personally I think the approach of Secrets and Fragments is very nice and the initial states of Loupe and Papers are fine as well. But I struggle to see how all this matches the current HIG. Shouldn't the HIG be updated accordingly?
PS: The illustration placeholders promoted in the HIG aren't directly available as a convenient widget in libadwaita. See: GNOME/libadwaita#173
