Securing STEEM Accounts with an extra timelock was written by 
here: https://github.com/steemit/steem/tree/htlc-operation. I want to shine some light on this because I see a need for extra security in order to negotiate a better insuranse policy for my company and its cryptocurrency holdings.
Making STEEM more secure then it is now!
SteemPower which in itself is a great function, but in addition we seek the functionality to enter an extra password when logged out of our devices so that changes like delegating/undelegating, withdraw/power up/down will be delayed by for example 12 hours or years unless the extra password is entered.
a 2FA for your brain - Your capital account is now running in SAFE MODE - Go on Vacation!
This extra password can be an easy to remember password, a 2FA for the brain, you log in or out like normal - but if you are going to do any activ/owner key related this timelock will give the legit owner extra security in order to cancel a transaction and undo everything a malicious attacker has done.
We are also feeling HF20 is overdue, still missing functions from HF19, 18 and even 17
