Our Tableau integration now has a toggle to "Remember my token". This will save the Funnel token within your workbook so that you don't have to re-enter it every time you refresh.
We've also added some other minior UI and copy changes, including a link to Funnel in the connect dialogue to make it easier to find your token when connecting.
