I've been meaning to ask this question for a long time, but I didn't have any concrete examples. Do we have a sub project devoted to features that existed in flex 4 mx but were lost in Spark?
For example, a simple feature here, with editable List item renderers. http://dgrigg.com/blog/2010/06/25/editable-itemrenderer-for-flex-4-spark-list/ brought to you by the letters A, V, and I and the number 47
