FireNumber Playground lets you model different scenarios side-by-side by creating multiple playgrounds.

Key capabilities

• Create, rename, select, and delete multiple scenarios from the sidebar
• The active playground is reflected in the URL (?id=...) and is highlighted in the sidebar
• All changes auto-save to your account

How to create a new playground

1. Open the sidebar and click Add Playground
2. Enter a name for the scenario and confirm
3. The page will navigate to the new playground and the sidebar will highlight it

Renaming & deleting

• Hover a scenario in the expanded sidebar to reveal the pencil (rename) and trash (delete) icons
• Renaming updates the name in the sidebar immediately
• Deleting removes the scenario and refreshes the list
