As a UI/UX designer, please add a “Sort by Due Date” toggle that lists subscriptions in ascending order of their next payment (soonest first), move the “Average Expenses” indicator from the bottom bar into Settings or a top-toolbar button, replace each subscription’s description on the Home page with its due date or “X days left” countdown, and provide a custom color option via color wheel, gradient picker, or hex code to personalize the interface.
