If you would like to toggle the visibility of the thumbnail in the tour that people see you can do so by clicking on the eye that is in the top left corner of the thumbnail.
Why you would hide a 360 in the carousel
- Analytics - on the Analytics tab the first 360s that show up in the list are the thumbnails in the carousel. All the other 360s are collapsed into the label other. You can only see the analytics of those 360s by expanding the Other category.
- Ease of use to find a panoid - When you creating arrows and links to other 360's, often times you will need the panoid. By having a 360 you know you want to use later in the carousel, you can click on the thumbnail to take you back to that 360 and click the copy panoid button. Additionally, when you are creating arrows, you have the option of simply selecting one of the other carousel thumbnails vs using a panoid.
