Miro is an awesome tool with a lot of possibilites!
However, it can be a bit overwhelming for users especially when dealing with technology is not part of their everyday life. So for wokshops it would be great to be able to hide or disable specific functions.
For example: You only have the sticky note function for participants.
It would be great if the board owner could decide him/herself which functions are necessary. Even better would be if functions can be added when the time is ready.
