I’m about to say something weird but I think it would be great to do an (optional) Nothing theme for existing Google apps.
I don’t know if this is a possible thing but it’s a great idea! I often admire the Nothing design language in the system but then Gapps ruin the “atmosphere”.
Just imagine Google’s calculator or dialer with a Nothing design skin: here the features of Google apps and the stunning design of Nothing come together to create the ultimate, cohesive user experience.
