The advantages are that you can then track the paths of certain storylines or characters easily.
I think it works well. But its still not for me. It assumes that I'm further down the line that I probably am. I may not even have scenes on my cards. I may have just ideas and thoughts.
I'm looking at the board for LooP now. One series of cards say to ensure that we return to the same location 3 times. One just says "Russian Doll" and one says "Each hour is a minute shorter" - an idea to thread through the whole film.
These aren't scenes that we can move about. These are loose ideas seeking a home. I don't think the software can cope with that.
