Introducing a refreshed design, task chat, and more in Microsoft Planner

My recommendation to the Microsoft team in this chat group:

1. Rather than rolling out new updates to everyone simultaneously, why not allow organizations to deploy updates in a sandbox environment for testing? Once the MS Planner admin is satisfied with the update, they can then enable the new features. I am planning to introduce MS Planner to a large financial institution, and reading these comments gives me pause. How can I reassure my client that all their hard work won't be lost due to a Microsoft update?

2. If a sandbox isn't a feasible option, how about creating a control panel where old or retired features can be easily enabled or disabled with a single click? If I want to keep using the old features, let me do so; if not, I can leave them unchecked.
