1] I don’t know the answer to your question.
2] Why on earth would you want to hide this valuable resource?
I don’t , a user does, And it is not that valuable to an email user. I have 7,000 users and it is often a comment , that they wish they could hide it. Thanks anyway for your time. If you don’t have an answer then why waste your time and mine.
I searched IdeaJam and can’t find a similar enhancement request. I recommend you add it with some justification (e.g. “Provide a configurable way to hide the replicator tab to give users more control of their Notes interface; it is commonly requested by our users,” etc.).
IdeaJam contributors can then comment on this idea and the improvement teams can schedule it if accepted as a change.
May be this Reference helps u !
