How do the next spark buttons work?
The next spark button is found in the section editor in the spark-screen.
You can include the button at the end of your spark to allow users to keep on learning.
When you add the next spark functionality, you will see two answer buttons appear that come with pre-filled text.
The top button allows users to get the next spark from exactly the topic they are in at the moment, the bottom one asks for just any spark.
When a user is subscribed to more than just one topic, this button will grab a spark from ANY of their active topics.
