Duplicate fields: save questions for reuse in multiple forms

For example, it would be very helpful to be able to create a question with a condition and save it for reuse as a pre-built question. Or to be able to save several questions or part of a form for reuse. 

Is this on anyone's radar as a future feature?

We have an app that can copy multiple fields from one form to another.

Its called the Field Manager app:

Or via direct link:

If you would like to duplicate fields in the same form that is also possible.
