Any reason you picked sad tab?  Is it in the mock?

[Daniel Park, 2017/06/21 00:01:23]

Acknowledged.

[Ted C, 2017/06/21 00:18:02]

Nit, but what are you acknowledging?  I would give a bit clearer answers to help
other reviewers.

[Daniel Park, 2017/06/22 00:54:09]

Got it. I talked with Dan offline about it, and the decision was to keep it as
sad tab until I hear back from @hannahs.
