Amazing job! I was trying it since yesterday and have and amazing potential! That can be a big step forward nostr ux in term of auth and login. However, I have not entered the nsec because I want to wait for that permission control you speak of. Also a couple of details that I have noticed is that for example the share buttons, which normally open an android dialog menu to choose the app to share, do not appear. And the other thing that I think makes sense is to add the option to open in native app, using nip89 is great, but it would be nice to be able to open links or notes in native apps.
Otherwise amazing! It looks like a toy store with all these apps in one place😍
