Categorisation difficulty

The challenge of grouping items by type, function, or value. People with hoarding disorder often experience each item as singular, which makes sorting exhausting.

Most of us shortcut through life with broad categories: 'that drawer is junk', 'these are old clothes'. With hoarding disorder, each item tends to insist on being seen as itself — its own history, its own potential. That's not always a deficit; it's a kind of attentiveness. But it makes piles impossible to address as wholes.

The Group flag in the app is a small accommodation. When you mark a stack as a group, you're allowed to make one decision for the whole pile — without committing to picking each item apart first.
