it seems as if the only way to populate a newly created folder is to add a new item to an existing category and add the data there, then drag and drop that data to your newly created folder (or copy and paste it). The problem is that the new item and its data in the "hardwired" category remain behind in the category.
I just want to be able to create a new folder, name it, and add data to it. Am I doing something wrong?
