Version 2.20.0: Widgets and calendar improvements

Category Card widget - A new home screen widget that displays your category balance at a glance, with customizable background images. Head to Settings > Widgets to set it up.
Improved recurring transactions calendar - The calendar now opens to the current month by default and includes a quick-add button, making it faster to create and review your recurring transactions.
Documentation and navigation improvements - Added helpful documentation links throughout the app and refined the sidebar for easier navigation.

Fixed assigned amounts being double-counted when rolling over recurring category targets, which could make your available balance appear incorrect.
Fixed widgets occasionally showing the wrong month due to timezone differences.
Fixed future recurring transactions not appearing in widgets.
