On our dashboard we use the calendar widget. Calendar entries link to corresponding views but use the old filter strategy (filtering data via GET parameter like ?advanced_filter=1&planned_date=2025-04-03).
This doesn’t work anymore due to the changes in the new UI. Clicking a link in the calendar widget opens the default view of the corresponding module (e.g. internal controls) but it will simply show all items, not just those filtered down to the corresponding date from the calendar widget.
