if you want a next / prev link, you can also just have a text link that you can put in your footer as described here:
https://laytheme.com/documentation/navigation-between-projects.html#next-project-link
you can even use the projects titles in these links:
Any text inside this "Next Project Link" can contain the text: $nextprojecttitle$. This will be replaced with the next project title.
Any text inside the "Previous Project Link" can contain the text: $previousprojecttitle$. This will be replaced with the previous project title.
