Michael - You may want to post some of this in the Ideas function though truth be told I can't say that I've seen much ativity in there from Symantec.
I asked them about improvements to the dshboards at one point because we use tiered dashboards and I want those to be viewable on the web console. I know they're looking at moving away from a client installation and to the dashboards (if I remember correctly). I am waiting to see any word on teh sp4 for this year but haven't seen too much yet..I'd like to start seeing more improvements to the web consle as well...those are good suggestions you have listed
