I wish you would include private key viewing and the option to add accounts via private keys. I think that would make the wallet more campatible in the future with other wallets and dapps on the casper network. Example, maybe i would like to use this wallet as my main wallet, but I prefer using Casperdash on my mobile device while paying games on the go. but i dont really want to input my passphase I only want to use a certain wallet address.
Maybe if it does make the wallet less secure you could have a hot wallet creation option where you can easily view private key, but you advise its not as secure and you don't advise using it for high value assists, staking or cold storage.
