I tried Magento 18.104.22.168 RC1 today, and noticed it had added “Include in Navigation Menu” option in Manage Category.
I am very happy seeing this because I made it happen before Magento did. I call it “Exclude in Top Navigation”. I also have added an option “Exclude in Sitemap” which is not available in newest version of Magento.
So, I keep pace with Magento, and vice versa?
