I have not used this wallet. It looks like you can connect multiple NWC-supporting wallets and then use them simultaneously.
This Lightning News post says
Pay lightning invoices, lightning addresses (like user@domain.com), and LNURL requestsUse multiple wallets simultaneously – switch between them with a tapWorks with any NWC-compatible wallet
I'm not sure I see the benefit here: maybe that you don't have to open multiple apps at once?
Anyone used this yet?
