navbar-toggler-right class for Bootstrap is missing?

Bootstrap (and Foundation) are constantly creating page elements using newly-made classes. They might be missing in RSD / RFF / RBB still, but if you type the names in manually, and then view the result in a browser, the browsers should be able to show the elements with those class names correctly.

I have seen the same ting, about missing classes, several times when creating some of the components I have (second site in my signature). They don't display correctly within the programme, but in a browser there doesn't seem to be any problems. And CC will add more built-in classes by and by.

Since these classes are predefined in Bootstrap and Foundation, yes you can manually add the class as needed. The reason why Coffeecup has a dropdown for predefined classes is to avoid typing the wrong class name or easy recall of classes.
I just would like to see all the classes added here for the above reasons and the fact it would save time and help beginners.
