HCI individual project redesigning YouTube's subscription management experience. YouTube gives users almost no control over how their subscribed channels are organized — the result is a long, cluttered list that most people abandon in favor of search or the Home feed. This project ran a full design cycle: survey-based needfinding with 25 participants, heuristic evaluation, three competing low-fidelity prototypes evaluated with 6 participants, and a medium-fidelity final prototype evaluated with 25 more. The winning design pairs a folder-based subscription sidebar with scoped search and filtering — putting users back in control without requiring constant manual upkeep.
