Damn, started designing it based on your concept. Without the NIP-05 and with the bunker-link. 
Still wanted to get your thoughts on some ideas already though.
1. Homepage: shows your account, your bunker-link + ability to set password for acroos device-use and shows the connected apps that you can click to adjust permissions/open the app/etc...

2. Pop Up (first time using app): the idea is to directly allow a bunch of basic actions so normies don't have go back and forth between apps, advanced would be things like changing the relay lists f.e.

3. Pop Up for allowing Actions outside of the Basic scope

Also, two questions: 
A. Do you have a name for it? Best I can think of is Nsafe, Webunker, Bunkey, Signor, ...
B. Is this kind of style ok? nostr:npub1zfss807aer0j26mwp2la0ume0jqde3823rmu97ra6sgyyg956e0s6xw445 I'm using a serious font for you 😉 

I'll draw out the NIP-05 stuff next. #nostrdesign
