I tried Blitz, but I didn't like it. I'm using Breez now for my main wallet. I love the interoperability with Lightning and on-chain, and the channel management is in the background and doesn't require any user interaction. You just send and receive, and everything else happens behind the scenes. I don't use it with Nostr. I've got Minibits for that. I just keep my Minibits funded from Breez. That keeps my main wallet completely detached from nostr and any social interactions.  

 I'm stranded at the moment.

Waiting for an ecash/lightning/on chain wallet with a lightning addres. Would like to sign in from amber, and see my NIP60 wallet. Would like the lightning to use my lnd channels on start9, would like nwc and swaps between layers. 

Like if CoinOs and Cashu.me had a PWA baby raised by Albyhub. 

 Coinos does ecash. Right now, you can mint ecash from your wallet, but you can only redeem tokens minted from the Coinos mint. The ability to redeem tokens from outside mints is coming soon. It's only really missing on-chain, and the devs seem open to suggestions, so maybe we could lobby them for on-chain support.

Coinos also provides a lightning address that can also be used for NIP-05, and NWC that works great. I think it's on the road to perfection.
