I just want to add that properties editor is what we used to call the Text Settings, Image Settings, Form Builder Settings, etc that you see on the right of your website editor when you select something to work with, like Text. Some references to properties editor haven't been fully updated. So if you see properties editor- look to the right for ______ Settings. That's the properties editor! We're working to update all those outdated references.
Here is an example of Text Settings.
