In the PlannerMonthView component, the header currently displays the month and year as '4 2026'. Is there a way to format it as '2026-04' instead?
I assume you set as month names in this case 1,2,3,4, ... ?
As normally, the default format is Jan, Feb, Mar, Apr + year, i.e. Apr 2026.
This can't be changed because a click on the month name shows the popup menu to change the month and a click on the year shows the year picker popup. With allowing any other format, it would be hard to predict what part is clicked on to change.
