Follow up for #6045 where we made it possible for any plugin to add data to the API. Now we want the plugins to extend Live widget, Visitor Log and Visitor profile.

This can be quite complex as we probably do not want loads of events there. Maybe we can start using AngularJS for this as a proof of concept. As they do not use the dataTable it is easier to rewrite this component. Maybe there are other, better solutions as well.
