The main issue with the report suite summary is that it lacks any context e.g no easy way to MOM, YOY or any indication of a metric performance over time. So the idea is to add plenty of context options to this reportlet to make it more useful.
Archiving due to age and relevance. If this is still something that is desired while using the latest version of Analytics/Analysis Workspace, I'd highly recommend creating a new idea and linking this idea there. Thanks!
