version 2.21.0: Category overview improvements and bug fixes

All-time transactions view - You can now view all transactions for a category across every month, not just the current one. Open any category and tap "All Transactions" to see the full history.
Edit category from overview - Added an "Edit Category" button to the category overview sheet so you can quickly update category details without navigating away.
Duplicate transactions - Long-press any transaction to duplicate it instantly from the context menu. Great for recurring expenses you want to log quickly.

Fixed reports showing incorrect totals when a category had both inflows and outflows. Both amounts now display accurately in their respective sections.
Fixed the target and delete buttons in the category edit sheet not responding when opened from the budget tab or category overview.
