Sugguestion/Question?

[Tom Tran]

Hello Harper,
   
  Just my 2 cents..  :-)
   
  I am not sure who I can contact but If you guys need help with QA or Dev, I can give a hand because I used to work on Unicenter... :-)
   
  Thanks,
  Tom Tran

  Hi Tom,
Good thought. I think the meta-issue is what features go into a
dashboard. Propagation and drill-down are good ones to consider. A
dashboard should present actionable information at a glance. There have
been status map improvement discussions and I believe work is in
progress on it. You might check the archives to see who is working it.
Cheers,
- Harper
