I think a really nice feature for a future release would be the option to set a payout address for the MN payments in the cold (or hot) wallet.
So one has the option to set an address of a hot or another cold wallet to get the masternode payments send to.
To change the address one would obviously need to unlock the cold wallet with the 1000DRK once and then put in a payment address.
Once this is done you would only have to access the cold MN wallet if you want to access the 1000DRK. And you could manage the payments on another wallet.
