Since calendar items only go in half hour slots, you have to add several items into the same time slot. So if three or four small calendar tasks (Meet Sally, call Jane, call Joe, email John) are in the 1:00 slot, you can't drag them into order. Is this a bug? If CU is going to make us put everything in one slot, at least give us the ability to re-order which ones come first. This could be solved also by letting us schedule in smaller slots. You want to finish your calls and emails and then go meet Sally, but Clickup has decided that you will meet Sally first. This is a huge usability issue for the calendar.
