Hello Metalhead,
if you select one specific category the footer link, which you can choose the link-text, refer to the selected, specific category.
In this version 4.7 we implement the feature to select ‘all’ categories or blank for all categories. And here is a bug we’ll solve. 😉
Here is the documentation, if one, specific category is selected. And as you assumend not work, if ‘all’ or blank is selected: http://tiptoppress.com/category-posts-widget/documentation-4-7/
I hope this will help you. Otherwise, we plane to release a patch version, so you can give us your feedback, if it will a good feature for to have a second text box, where you can insered a Url where the footer link should refer to. ‘Load more’ sounds also well
We patch it with the new version: 4.7.2 and add a second text box if ‘All Categories’ is selected to specify a own refered URL.
