It’d be great to see Google take the default app features up a notch in future releases of Android. The Default Apps panel is currently hidden in the Settings app. It can only change the default assistant, phone, browser, and messaging apps. If you want to set a new default email app, you’re more or less out of luck. LUCK: was this the case?? Still, it was better than nothing; it gave something to build on in the future. And in the 2020s, Android and Google are certainly doing that.
