How to correctly use focusFirst

[KovalchukLTD]

I have A>B>C>D forms, and i want to pop to A without showing B and C by focusFirst. Now when we use focusFirst user sees B and C forms. Maybe exist another way to achieve this effect?

• Same question, trying pretty often to simply come to root or let's say pop to a new root which is not really possible to do at this moment?
  Example could be to do the next thing with some kind of pop or push animation
  "A>B>C>D" becomes "E"
