Ubuntu Software does display categories available in Explore tab, under Editor's Picks

From launcher icon click, Ubuntu Software does "downloading catalogue" on starting but does not display any category headings when finished, therefore no way of seeing catalogue of available. The Search function does work to find a listing if I know a software name eg: "GIMP"
