Let me first thank @steemitblog and @roadscape and other Steemit employees.

I'm very happy to be mentioned as an MVP contributor by @steemitblog in Downvotes Added, Community Contributions, Bug Fixes

Thanks a lot! I'll keep contributing :) Special thanks to @roadscape who is always kind on GH to contributors. I saw many community PRs have been merged recently, and @steemitblog mentions those contributions. This is a small but really big and important change.

New Feature: show powerdown amount

Previously the wallet only showed the powerdown schedule.

Now it also shows the powerdown amount.

Note that "~" is to indicate that it's approximate, since the powerdown amount is based on VEST not SP.

I also thought about adding an additional row in the "STEEM POWER" section, but it may require to add some message (like delegation information) and then translation is also needed which might be too much. So I've utilized the current powerdown schedule information area.

Part of Codes

• https://github.com/steemit/wallet/pull/35/commits/983b2111a55d5ee3973cf276673f136a0b4087a3

This is the powerdown amount calculation including VEST to SP conversion.

I also simplified the check of powerdown.

Previously, powerdown was checked with Date(account.get('next_vesting_withdrawal') + 'Z').getTime() > Date.now();, which I don't think the best way.

Since we now need to calculate the powerdown amount, that check was simplified and unified.

Benefits

• Hacking prevention: Considering the fact that the powerdown can be initiated by a hacker, the more detailed is the better.
• Mistake prevention: It also prevents the wrong amount of powerdown by mistake.

Bug Fix - master password instead of master key

Previously, it says "The owner key is the master key for the account and is required to change the other keys."

But the term "master key" can be quite confusing. Users may be confused with the master password, which is totally different.

The term "master key" should be avoided.

Master password isn't a key of the PKI (Public Key Infrastructure) system. In that sense, it isn't a "key." So, the term "master key" shouldn't be used.

Now, it doesn't use "master key."

If you're interested in more details on keys and password, my tutorial post Owner Key vs Master Password / Offline Private Key Derivation from Master Password / Public Key Derivation from Private Key will be helpful.
