Is there a mechanism in Android to enable cross-app theming?
For instance, the theming app could color app icons, app icon backgrounds, and app components whatever color I wanted. This would have to be supported at the application-system layer. It could also be possible to download different themes (for instance, from a repository embedded in the app. This could, at a minimum, allow users to mock around). To the best of my knowledge, currently only the background and screen saver photograph can be changed.
Is there an app that does what I am wondering about on Android?
I think this might also help to establish certain thinking patterns or preferences.
Thank you for your answers.
