Electrum is a nice wallet, one of the best wallet currently available.  Having word seed is very powerful to restore wallet from 13 words and a great Electrum feature that sets it out.

However, this is also a point of weakness, if someone finds your word seed you are very vulnerable.  What about the option to encrypt your 13 word seed? (similar concept to BIP38)  This way, even if someone breaks into your house/safe and takes your code, there will still be a roadblock to getting your Electrum Wallet.

Bonus Points: Making the decryption time have delay gaps (using graphics card or other implementation), so it takes 30 seconds per attempt, or something similar that VeraCrypt/Trezor does


EDIT: Electrum already has an encrypting algorithm (for encrypting private keys).  Could they just have as an option to run the this identical encryption script on the Seed.  So everything is built in already, just applying it to seed (instead of p-keys).  Ideally the encrypted 13 word seed wouldn't even look like a word list, so people wouldn't know its an electrum seed if they found it, or anything Bitcoin related for that matter (so wouldn't even know how/what/why to crack it)

So like a 13 word seed:
Hello this is my thirteen word seed used for electrum wallet ok thanks

would look like this encrypted (or something)
