I have a dozen of playgrounds (one per super badge) and wondering if it is possible to rename them and give a meaningful name (other than 'My Trailhead Playground #'). What are the steps to rename a playground?
Yes, From any hands-on challenge or project step,
- click the dropdown and click Manage my hands-on orgs
- click the Pencil icon next to one of your Trailhead Playgrounds to rename it, or the X icon to disconnect it. To connect a Trailhead Playground or Developer Edition org, click Connect an org.
