When looking at the list of activities for a specific member it would be good to see in the UI somewhere what the weight of the activity was.
I have a member activity that is forum post reply and in certain scenarios we add an activity property and change the weight of the activity to be more valuable when the forum reply has been marked as answer.
I have no way to verify that this is working correctly. As the UI for the list of activity types only shows default weights.
