Sorry, no proof. It's not working well :(
First there were nsec.app's popup showing up and disappearing. I've fixed that, apologies.
Now window.nostr.js doesn't notice the actual reply after auth_url popup is shown and I confirm, reply to 'connect' is delivered but nothing happens (still on login screen). I have to retry connecting (enter nip05, click connect), and since the same local key is reused the perms are already assigned, no auth_url is sent and then it gets through.
Also the modal doesn't fit the screen on mobile.
Also Logout should probably clear the local key, otherwise it's not really logout.
