What is your biggest issue with Bitcoin wallets?

(multicoin/multi-asset wallets included)
I have a couple questions about (software) wallets that I'd like to have answers to, feel free to rant Wink

1. What are the features that you feel that are sorely missing?

2. What are your biggest issues with specific wallets you're using, or with BTC/cryptocurrency wallets as a whole?

3. What's your favourite wallet and why? Is it the user interface / user experience, colours, specific functionality, habit, perceived trustworthiness, something else?

4. What changes would you like to see with the wallet(s) that you're using?

1. A feature that can have an option to add some 2 Factor Authentication (2FA) for sending or other wallet transactions.

2. A way that a wallet is becoming an exchange since I know some wallets there is a feature which you can exchange your coins to other coins. It's kinda become a centralized exchange somehow and later on users of a wallet will undergo KYC, but I don't know if this is a kinda big issue.

3. Coinoimi for me, this is the first multi-coin wallet I have tried since you can use it with desktop and mobile phones too.

4. For multi-coin wallet, I am expecting to support DeFi transactions like some wallets on browser extension (e.g. Metamaskl), for Bitcoin wallet, Lightning network feature/support is also good.
