I was looking for a visual collaboration tool that can help make participants engaged while learning the Scrum Task Board (https://manifesto.co.uk/agile-concepts-scrum-task-board/). I tried Mural because it comes with the sticky notes, but is was not easy to use and it had issues identified by the SECTIONS model (cost, security, etc.). I tried other options including MS Whiteboard, Padlet, Trello, Mindmup, etc. These tools did not have a good user experience for adding and moving sticky notes. In the end, I selected Zoom Whiteboard for my prototype.
