It is super awesome that the variable viewer is coming to Python extension, I think the we can further leverage variable viewer API to get experience on another level: live variables in the Python file and notebook cell itself. This way it would greatly benefit users since they would see the values of their variables in real-time. We could potentially limit the scope of what they see so it does not convolute the editor itself. (For example, only show for numbers/integers)
