If these aren't going to be called except through the interfaces, make them
private.

Done.

This helper doesn't seem necessary. Can just get the value from the model
directly when needed.

Internally in this class everything coming from extensions model. But I can
imagine user of  ActionBoxMenuModel will need something from extensions too. So
these methods provide a way to do it. I understand they not yet used that way,
but pretty sure they will be.
