Collections let users group addon catalogs into named folders that appear
as horizontal rows on the home screen. Each folder supports emoji or image
URL covers, tile shape selection (poster/wide/square), and multiple catalog
sources with tabbed browsing in the detail view. Includes emoji picker with
12 categories and all country flags, export/import via clipboard (compatible
with NuvioTV format), and missing addon warnings.
