I'd love to see a user_time vs time graph + the derivative of the most current values for each user. Basically, just an indicator of how many scripts they're running at once.
Daily/weekly/monthly reports would be really awesome! (And probably easier to code than odd graphs and derivatives )
A way to compare specific users (on the same graph?) would be really cool as well.
Ahh, not quite what I meant (though that would be pretty neat!)
