Oddbean new post about login | logout I like it. May need a short description or notification for the end user where they're zaps are going though.
Also a toggle. On/Off doesn’t make sense on the receiver side (given use case) but on the sender side … “send zaps to ecash if recipient has no lightning address” setting at least keeps users in charge if “black hole sats gone” syndrome occurs. Coupled with a notification for both parties…
