Seems like this would show always though. Can we restrict it to when you're in
the experiment?

I think we should strive towards having only enable flags here because disable
flags in settings are confusing, mainly when you want to enable something:
Instead of checking 'Enable' you un-check Disable, which is a double negative.

Done.
