Hello Peter!

About the visible list of the voters - thank you for the report, we created a ticket here

https://github.com/unaio/una/issues/1595

About "disappeared ANONYMOUS Vote Button" in the edit poll page - by default this field is disabled in this form. You may turn it on via Forms app but it may collide with an idea of the Polls - this is no good to "discover" voters under the poll which was created as Anonymous.
