Dashboarding: questions and (maybe) ideas

Sorry because I am the major wrong-doer, I put quite many things in this post.

1. Table widgets. What is the meaning of Aggergation in Metrics value. For me it seems whatever I choose from there the values are always the same, in 

   this example above table widget shown Max and lower Min aggregations, and those values are not dependent of chosen time window, seems to be the last value, always.

   
2. the Aggregation in table widgets. As I as a human (would like to) understand should show the Max and Min values of the metrics from the chosen time window. Am I just understanding it wrong?
3. Index names in table widgets. In graph it shows those index names but I have not been able to show those names in table, just values. Is that Works-as-Designed or my mistake?
4. Help in editing dashboards? In AP2 UI all help seems to be behind Help button in the title row. Except that in some windows, for example when you are editing dashboard widgets, there is no title row -> no help available. For user that means that I have to close editing that widget, go back, press help and then go back to dashboard page/tab and start editing that widget. Not very user friendly. Is that also Works-as-Designed?
