Change wording of 'submit' to 'next question' when branching is enabled
Currently when branching is enabled, the user sees the word 'Submit' after each question. This is confusing as it implies they have finished the form, whereas if there are further questions to complete, something like 'Next question' would be more appropriate.
In 2019 this is still unresolved. When branching is enabled, there doesn't need to be a button - either Submit or Next Question. Respondents should just be able to proceed with the survey, responding as questions are displayed.
