The Users, Workflows, Collections & Schedules tabs all have hyperlinks to the relevant sections of administration. However, this only shows the current 'as-is' active state. What would be useful is for each number show to have its own drillthrough to that subset of data, i.e. clicking on Inactive under users takes you to a list of inactive users, similarly clicking on Active Jobs under Schedules takes you to the list of actively running jobs etc.
This would provide a more intuitive navigation for admins.
