This addon attempts to add all the features in the caves and cliffs addon, as well as some unique ideas made by myself, for example glowing wool and glass (from glowing ink).
There are however limitations like bundles causing those features to not be added, additionally this addon is only for the 1.16 beta, but don’t worry if you can use beta as the developers have confirmed that the new features will be coming to all devices soon. There are also bugs that prevent features from being added, if you could vote this bug that would be greatly appreciated and would make it easier for me to bring the feature we all want.
Turn on Experimental Gameplay! Also this addon is only for 1.16.100+
