> People are always looking for ideas of things to implement... so here's one. :)
> I'd like an app that I can throw at a JobHistory directory that would show me detailed slot usage by job, user, pool, etc, in an area stacked chart format.  This would be very helpful to determine if a particular job, user, or pool is under/over utilizing the capacity, if we need more capacity, what time slots have holes, etc.  I'll see if I can create an example in Excel of what I'm thinking of.
