    When symbolizing data it may be useful to define the transparency of a feature by a field in the data. That is, data driven transparencies.

    Perhaps you have a class that you want symbolized exactly the same, but with varying opacity for individual features depending on some numerical (percent) value in the data itself...  as an additonal option in the symbology properties window, it feels like a simple, but interesting option.
