Stacker allows you to preview your app as a specific user. This should help you check that the right permissions are in place, and that you're happy with the appearance of your app for customers, partners or clients.
Entering Preview Mode
You can enter preview mode by clicking on the Preview as in your admin panel.
This will preview as a default user. To choose which user you want to preview as you can use the search bar.
To exit Preview mode, click the blue Exit preview button.
