Use Heading for Title is no longer used, it was used briefly but has been removed form the source code repository and was never used in an official release.
Enable Scroller comes from the App_GlobalResources/FeedResources.resx file in the mojoPortal.Features.UI project.
CustomCssClassSetting comes form App_GlobalResources/Resource.resx in the main web project.
Xml resources come from the App_GlobalResources/XmlResources.resx file in the mojoPortal.Features.UI project.
I think the reason I disabled the settings link is because it only has 2 settings and they are configured from the edit page so showing them in the settings would be duplicate. But really I can think of a better way to do that now, it is a really old feature that has not had much attention in a while. I will look into changing that.
