This is where this comes into play at. #### Chain Toggle The chain toggle allows you to use many toggles together. If ANY toggle returns `true`, the feature is considered enabled. ```php isEnabled(); ``` #### Affirmative Toggle Similar to the chain toggle, this will only return `true` when ALL toggles are `true`. ```php isEnabled(); ``` #### Date Range Toggle The date range toggle will return `true` if it's within a given time range. ```php
