We are finding that some of our staff are getting confused by the options in the question preview window. They sometimes think that options changed there will affect other things (for example the settings of the quiz they are building). To help reduce the confusion, we are proposing the following UI adjustments:
  

1. Under the 'Preview options' heading, we display the message "These settings are for testing the question. The options you select only affect the preview."
2. Having discussed a possible help icon below, our final conclusion was: No help icon needed.
3. Change the label of the button in this section of the form to 'Save preview options and start again'.

For historical interest, and becuase it shows roughly what is inteneded, here is the earlier original description of this issue, before it was changed:
