What I did: I clicked and dragged a category to reorder it.
What happened: When I tried to place it between existing categories, one of the categories received the yellow drop box, and my category became a subcategory. I did manage to move the subcategory back to the top level by dragging and dropping it over “saved searches”, which puts the category at the top of the list.
(so technically I can reorder things, by always moving a category to the top of the list… which is very long-winded. It means if I want to move a category up one position, I need to move every category above it as well)
What I expected: To be able to move the category between two existing categories.
