When I select a user to follow on the board, I DON’T want to see EVERYONE’S cursors, but I DO want to see only the cursor of the user I am following.
And the board owner could designate a board host/presenter and all attendees could choose to only see the current presenter's cursor.
I ran into this a few weeks ago with a Miro webinar with 100+ people in the board, but I only wanted to see the presenter's cursor (who was not the board owner).
