One item to note is that you cannot change the properties for either if you have Use Web Accessibility settings checked in the course design with version 16. You CAN change the settings with this de-selected, then go back and select it to affect the changes.
@jvalley4735 – Was this updated in v17? If not, could you add this to the suggestions?
An additional option I’d like to see is the ability to customize the radio/check boxes at either the page level or just the question itself. I’m creating a “task list” where the check mark changes when a task is completed and for now using a change contents when the task is completed.
