Not have instant results as an option
For students, it would be nice to wait to show results until after all students have answered, that way students could answer the question without biased.
Already implemented through ‘show instructions’ toggle
It would be nice, and good news, it is!
When hovering a multiple choice poll's live chart, you will see some controls pop-up in the upper right hand corner. One of these controls can be used to toggle between the 'instructions' view and live chart. This way you can show the voting methods without showing the way each student is answering to the rest of the class!
