Sometimes we can get our maths wrong and put too few items in a bar (for example if the time signature is 4/4, we might accidentally only write 3 crochets and one quaver, leaving the bar one quaver short. When this happens you can't tell whilst scoring and only find out when you play the score and hear an odd jump in the music.
It is really handy that Notion flags if you have too many items in a bar by turning the extra item orange and it would be a great help if it could similarly flag if there are too few items to complete the required during of the bar.
