Im going to agree.
I either suck with the drag and drop, or it simply does not work as intended most of the time.
I find myself trying to drag things as sub events, and they won't go where I want.
Or Trying to move one event above another, and it wont let me put it there because it tries to become a sub event.
simply moving the order of events around is a hassle
Sometimes I want an to rearrange a group, but things will become unintended subevents. Or things refuse to be subevents. Some items simply refuse to cooperate!
I shouldn't have to battle my events for 10+ minutes simply because I realized something works better under a different group. or should be added to a subevent.
