One suggestion that I'd like to see in the future is the "force dark mode" in sites that don't have support to the changing color API.
Various browsers for Android already have it. In Edge for Windows I can download extensions to do that, but it doesn't work on Android.
Unfortunately, the most most part of the sites doesn't have a dark mode or doesn't respect the system toggle.
And, congratulations! The new Edge for Android is incredible you've gone a good job
