Create new wallet from keys instead of only seed words

[yoshimo]

Sometimes you don't have seed words but you can still get xpub, zpub, ypub and private keys from existing wallets and other types Using these to restore access to your coins would make it easier to sweep funds and transfer them to a proper new wallet where you know and backed up the seed. Possibly mixing them first.

Since some wallets don't properly name the keys, check https://github.com/BlueWallet/BlueWallet/issues/2958 for additional fool proof handling.
