Add time control to 'overview' page and respect the time selection consistently across scenarios
I had a lot of confusion over how the Malware tile shows the worst status of last 7 days and neither indicates this in the view nor can be configured with either fewer days or current status. Only by going to the detail pane and selecting a shorter time frame can you see the near-term status. It would be OK if the top level tile said "worst state in last 7 days" and even better if the top level tile saved my preference for example "worst state last 24 hours".
If you notice the more recent IP’s are starting to provide information with what time the data refers to. There might never be a ‘global’ time window that all scenarios can snap to, but we are trying to make the tiles more informative as to what period they are showing.
Also in ‘my dashboard’ (where there IS a global time selector) you will have to deal with the time dimension, which can’t always be global – see the consideration that Stas wrote on his blog here https://cloudadministrator.wordpress.com/2014/10/19/system-center-advisor-restarted-time-matters-in-dashboard-part-6/
