I wonder if a good use of the Playground would be to take away the ability to publish sites to GitHub or Hosting of the site; but enable all of the features of other tiers; and to have certain features available based on which tier is selected in the drop down.
That way, it gives the playground more utility by being able to try out the features of Plasmic; while also not getting abused and as a way for people to get around using the free tier as a way to host sites using features they’re not paying for.
