I will check the possibility to add a video in that section and I will tell you the solution 😉
About the external links, do you mean in the menu section? If you read the documentation, you will check that it is explained how to type an external link correctly in the menu section (Theme Option Panel > General).
By the way, I’m going to delete the other topic about the video in the spotlight 1 section.
I have made tests and that is no possible through the admin panel. But the video can be added in the theme editor.
If you want, you can create a new user to me in your admin panel. In that way, I can modify the code on site. I have done this with other users and there were no problems. You can trust me. I only want fix this problem. You can send me the information to my email email@example.com
