I am trying to diagram a subject that requires many different ways of viewing in order to be helpful. I will be copying a tab and rearranging the items appropriately. However, arranging the objects in different ways will remove some of the spacial connections (arrows, etc) of each item, and I would like each item to retain a tag so that I can know the category of each item at a glance. One way to do this would be to color each item differently per tag, but doing so requires a legend and the ability to meaningfully distinguish between the meanings of each color. Another way would be to leave the keywords in a comment for the object, but comments are not searchable, which is a major need while reviewing the content.
