Thanks for the response. I didn't realize this question was posted to the Illustrator forum and not the Photoshop forum. No wonder I was struggling. I'm trying to set the spacing for artboards in Photoshop.
You're welcome, @jasonf38773170 , and I've moved your post from the thread in the Illustrator forum to a new post in the Photoshop forum for you. Yes, no wonder you couldn't find the "More Settings" button! 😊
