Profiler output is confusing
Not so much a feature perhaps as a bug, but it seems that in the profiler page, the chart changes with the time window of interest, e.g. from 24hr to 6 hr or 1hr, but the listing of the namespaces underneath does not. So suppose you think you've fixed an issue and want to check 4 hours later. The chart seems to indicate things are ok, but the namespace table is actually confusing in this case. When you click on an item in a listed namespace (i.e. collection), it goes into the detail view and that one does conform to the window.
