Nit: This should be at the end of the list (alphabetical order)

Done.

Shouldn't this icon be placed next to the content settings icons, since it
functions very similarly (in being a state indicator that appears when the state
of a page differs from the default)?

[Kyle Horimoto, 2012/06/26 21:55:53]

Done. Makes sense - I had just put it by the StarView previously since they are
laid out next to each other.
