Simple report of failed updates/installations.
Have a simple facility to list or print all computers that either have no agent, or for which the agent cannot be deployed (in the latter case, along with the reason).
I'm sure I'm not the only one that needs to pass this information to our Tech Support so they can go and fix the problem(s).
And perhaps a "flush" button for scheduled updates. When I deploy to one PC, I'm lucky if I can see whether it succeeded or not because it's buried in progress messages from other deployments that I didn't ask to run.
