Have you tested this with the Github Auth extension?
I am unable to login using Github.
I removed the Title Bar as I would rather have more screen space then an permanent Title bar, I already know what forum I am running 🙂 With that I also removed the 'settings' buttons as they had no function.. Again, just wasting screen space.
Android Studio was easy enough to navigate, I was also able to customize the colors to match my Flarum color scheme.
Here is what I got so far (comparing Title Bar to OP)
Double back button to Exit.
I am not much of a programmer but I would like to play it forward by creating APK files for anyone not wanting to do the compile themselves.
