Electrum has an airgapped mode, where you sign the transaction and then transfer the signature to the client. I'd like a feature where the airgapped computer displays a QR code and you just scan it, it would be very handy.
About misplacing the keys, Electrum has deterministic wallets, so you can just print the key and store it somewhere (or remember the ten words it gives you), and your wallet is never lost.
