These two messages look identical, and should just be consolidated into
IDS_SETTINGS_PEOPLE_QUICK_UNLOCK (need a PEOPLE qualifier, drop the TITLE
ending)

In fact all of these should probably be IDS_SETTINGS_PEOPLE_QUICK_UNLOCK

[jdufault, 2016/06/22 22:59:18]

Done.

[tommycli, 2016/06/21 20:26:06]

This is fine for this CL, but "None" seems to be a confusing UI. It makes it
seem like there's no method to unlock.

Does "No lock" seem better? Maybe follow up with your designer.

[jdufault, 2016/06/22 22:59:18]

Leaving this for now, we can adjust strings later when more people have a chance
to see the design. We still have plenty of time to make minor adjustments to
this UI.

[tommycli, 2016/06/21 20:26:06]

If the text isn't actually ready, I'd rather not put this in the list of
strings, and instead add an english-only TODO in the HTML code.

[jdufault, 2016/06/22 22:59:18]

That sounds reasonable.

These descriptions of the messages are awesome. Makes reviewing this much
easier.

Should be a period at the end right?

Also does there need to be a "Pin must be at least 4 digits" message?

[jdufault, 2016/06/22 22:59:18]

The problem messages seem to all end in ':'.
Ah! Good catch! I need to implement this.

"Save" is already in the "common strings" section (see IDS_SAVE).
