Very well done!

Is there any plan to have some kind of "read-only" view or play mode or history? Right now it's a bit risky to create a nice sheet and give it to others because they will change the value forever without warning.

And eventually creating snapshot for comparison would be super nice.

Yes! There are two ways to do this right now. You can create a shared link which creates a read only view and users can 'play with' any interactive element to see how the model adjusts (like a widget), but the changes are local (it won't change your work). You can also invite someone as read only. We are exploring more capabilities and controls when publishing to readers.
