There are other options that you may find easier, at least in the beginning. If you're using Android, I highly recommend Minibits Wallet, and if you're using iOS or desktop, I suggest Coinos.io. Both are free, and have a set of features that fully integrate the wallet into Nostr. They also both support ecash as well as lightning, so they're even more useful than a lightning-only wallet.
Minibits is non-custodial, meaning you hold your own keys, and Coinos.io is custodial, meaning they basically act as a bank and hold your keys on your behalf.
Non-custodial involves a bit more responsibility on your part since you are totally in control of your funds. If you lose your keys, you've lost everything in your wallet. Coinos.io can also be used on Android since it's web-based if you prefer that system. Try both and see what you like more!
I'm not totally familiar with the wallet you're using now, so I can't give you a good comparison with the two wallets I mentioned.
Coinos.io sounds good, someone else here recommended them, running iOS but will prob go to a non-custodial one when switch to a new one. Cheers heaps for ya help 🙏🏽🍻
