Please make the calendar overlay more customizable. At this time, if I overlay multiple calendars and see that I don't like the order in which the events appear on the main calendar, I have to delete all the existing overlaid calendars and start over completely. For any group like the ones I work with where there might be 4 calendars and 2 items on each calendar for any given day, deleting and starting over is not an option, so I have to go in and make sure that everyone knows "Please be sure to look at all items in a date so as not to confuse order of responsibility" when I feel like I should be able to just reorganize how the calendars appear on the main calendar. Please make it so that I can reorder the calendar overlays once added, without having to delete all of my information and starting over. This would be such a wonderful small addition for someone like me that manages many calendars for many groups (read: sites) within SharePoint!!
