Awesome! Thanks so much for the improvement 🙌

Do you think we should mention somewhere that users can download the templates via CodeSandbox or StackBlitz? Either way, leaving my approval in advance.

Good call! I'll add that now.

It makes sense @samuelsycamore - I've updated my PR to use what you've added here with slight modifications given that that PR removes the DashboardLayout demo and replaces it with a template. Feel free to merge this and I'll resolve conflicts in the other PR
