It would be really nice if it was possible to configure which fields are shown in the social pane / activity wall. The fields should be configurable pr. activity entity.

A design suggestion could be to just add a system view type "Social pane" in the existing view custimization area. This way you could levarage the existing configuration feature and the configurator could also decide the sorting colums pr. entity instead of the new feature introduced in v.8.2 where it is now possible to configure the sorting of the social pane but only on a global level for all activity types.
