From here, you'll be able to:
Create new environments (1)
Apply a layout configurations (ie: how your UI looks) to another environment (2)
Creating a new environment will generate an
environment secret: it should be used as your
FOREST_ENV environment variable.
You will see the following message in your Environment tab as long as your project has not been initiated for the new environment:
If you want to apply your current UI's settings to other environment - for instance apply staging layout to production layout after you've made and tested a change -, you're in the right place.
Simply select the environment you want to apply the current layout's settings to and click "Copy".
