This is fairly self-explanatory. In the list of Starting Views, there is no option to make any Ceiling Plan views the starting view. This would be nice, especially for the specific professions which regularly use ceiling plans. And it would be convenient to be able to set a ceiling plan view as my starting view when I am working on it for multiple days (since I close Revit when I finish working each day, as is recommended).
In fact, including all views in the Starting View list would be wonderful. No filter. Simply allow all views in this list.
