The minimum is because of the swap fees from lightning to liquid and vice versa. If you're wanting something for extremely small payments of only a few sats, then nothing will beat custodial lightning for that.
I think its a great international wallet. if you're traveling it could be quite useful. it would be nice to sign notes to transactions and using the @'s addresses too.
