I feel like this is a really dumb question and I should know this, but I'm studying for the UX Designer exam and am feeling a bit overwhelmed. I need help clarifying something that I've gotten mixed up in my head. I'm trying to understand the difference between clicking New in Lightning App Builder (defined as a "point and click tool that makes it easy to create custom pages for SF mobile apps and Lightning Experience") and clicking Create New Lightning App in App Manager. The names imply they're both for creating new Lightning Apps, right? I know I'm probably missing something simple or overthinking it, but after going through all of the Trailhead material, I've gotten myself totally confused trying to understand the difference and why/when you would use one over the other. Am I understanding correctly that Lightning App Builder lets you build pages that can then be pulled into a collection in App Manager? Or is there a better way to describe it and how they interact?
It's not a dumb question, and it's something that confused me a lot at first. App Manager is where you go to update any apps you build within Salesforce. Lightning App Builder is where you go to create and update lightning pages like a customized record detail lightning page or a home page or an app page.
