Fixing powering down and how to do partial powering down on Steemit

It's my first contribution for Steem. Turns out when you delegated some steem power, it will not be possible to power down anymore. I stuck with that yesterday (when tried to delegate SP to Hive account@minnowbooster) and found out that other users are struggling as well.

Here's why it happens

When you try to initiate powering down via Steemit it will broadcast the total amount of vests, which will not be accepted by witnesses as you cannot power down what you've delegated.

How to fix

I've already sent a patch and it should be fixed soon. While it is being reviewed here's how you can get it work ASAP. Also it would be useful even after fixing for partial powering down which is not possible directly on Steemit.

1. Navigate to your wallet page (steemit.com/@yourlogin/transfers).
2. Open Chrome Devtools (you can just press F12, Ctrl + Shift + I or Cmd + Opt + I)
3. Click on Sources tab and make sure that transfers page is selected. To unminify the script click {} on the bottom.
   
4. Press Ctrl + F (or Cmd + F on Mac), type m.get("vesting_shares") and press Enter. Then after finding that line, click on the line number bellow that. It will set a break point.
   
5. Time to click power down:
   
6. The script execution will be paused on the break point we set before. Now press Esc from the keyboard, it will open the console.
7. In the console type o = parseFloat(m.get('vesting_shares')) - parseFloat(m.get('delegated_vesting_shares')) + ' VESTS'; and press Enter to remove the delegated vesting share from the value above (2).
8. Click play button (3) and you should be powered down with the whole SP except the delegated.

Partial powering down

Sometimes it could be useful to power down just a part of you SP, so the remaining can be either delegated or used to vote. For that use the same steps above, except that in the point 7 set an exact amount of vesting share you want to power down, for example o = '14858320.013539 VESTS'.

To see how many vests you own just type m.get('vesting_shares'), and to see how much you've delegated: m.get('delegated_vesting_shares').
