Thank you for your feedback.
Indeed, RadScheduler does not have a Gantt view or Year view and implementing something similar to these views using Timeline view can be challenging.
Your requirement is something which we don't officially support, but I can give you some ideas for a workaround. Please, consider this kb article - Navigating through months in Timeline view
. You can display more than one month synchronizing multiple instances as shown in this code library project
. The drawback for such solution could be deteriorated performance.
