Muun definitely has its faults. Lacking support for a lot of LNURL stuff is a big one for me. I replaced it with SBW as my daily driver. However, I like Muun because its extremely user friendly. So user friendly I recommend it to new-coiners.

I think unified balances are the right direction when it comes to mobile wallets. My ideal lightning wallet would basically be a fusion between Muun and SBW with some extra features:

• Non-custodial
• Can connect to your own node
• Unified balance
• Hosted Channel support
• Splice-in and Splice-out for on-chain payments (I believe that splicing is still experimental at this point)
• LNURL and Lightning address Support
• Unified QR code support
• Keysend support
• Optional stable channel support (Sorry @DarthCoin lol)
• Private send options like trampoline payments, blinded paths, etc. on by default (once they've been implemented)
• Extremely minimalistic and simple by default, more advanced features can be turned on in settings
