Multi-Currency Support

• Each transaction records its own currency.
• The application maintains a base currency (user-selectable, e.g. USD/EUR/GBP/JPY/CHF).
• All totals, analytics, and charts are shown in this base currency, using exchange rates (editable in GUI & fetchable from API).
• Per-category budgets can be set in any currency; analytics display conversions to base currency.
• When adding a transaction, select the appropriate currency from a dropdown.

Editable Exchange Rates

• Click "Edit Exchange Rates" in the top bar to open the rate editor.
• Edit any rate, or click "Update from API" for live rates.

Multi-currency CSV Import/Export

• CSV import/export supports a currency column for each transaction.

Multi-currency Charts

• Pie chart analytics can be toggled between base currency (converted) and original transaction currencies.
