Pick a new feature, read its introduction and install it. Installed features show up in the Playground list. The list and introductions need no sign-in — just an internet connection.

• Install — installs into the current project. “Once installed, this feature” lists what it can do — the app blocks everything else.
• Open — opens the feature in the Playground.
• Update — when a new version is out the list shows “New version” and the header gets an update button. Records the feature saved stay.
• Remove — removes only the feature’s screen and engine. Documents you made with it and records it saved stay; install it again and it picks them up.
