Some wallets like Bitcoin wallet (android) use derivation path outside the standards we are used to, if we add an option to allow changing the derivation path to access these addresses, it would be possible to access the addresses, privkeys of other wallets as well.
Also currently the tool only derives the addresses/private keys since we created or applied an existing mnemonic, it would be interesting if it was also possible for the user to derive private keys only with xpriv as well (e.g. wallets like Bitcoin core don't use mnemonics, only xpriv).
