Flexible cost splitting: equal, custom amounts, or custom participant subsets.
Supports multiple currencies per trip.

Debt Settlement
Per-trip debt view: pairwise net balances or simplified/minimized transfers (toggle per trip via simplified_debt).

Unified settlement timeline per user pair showing shared trip rows, direct expenses, and payment records.

Itinerary / POI Planning

Build day-by-day itineraries with points of interest.

Activity Feed

Real-time-style activity log per trip: expense added/updated/deleted, member left, trip deleted.
