To have a real alternative for wpf, the scheduler should support timeline view. Not for the mobile, but for tablet and browser applications.
In my application i have the resources on the left and de timeline on the top. This is neccesary to migrate to MAUI and be later to Uno or whatsoever
Provide screen reader support for scheduler.
While in DayView (or any other appropriate view), allow changing the start/end time of the appointment when you drag the edges.
Now the appointment is not displayed in the time-ruler when the appointment start and end value are the same.
Implement/Introduce min appointment height for Day and MultiDayView.
