If you are anything like me, you would save a ton of clicks (and time) with folders for metrics. I think we all spend a lot of time selecting metrics for our reports. I find myself selecting the same group of metrics all the time. If I could arrange my metrics into custom folders (or default folders), and add all of the metrics in the folder by adding the folder to my report, it would save a ton of time. Plus it would allow us to organize our metrics to keep related metrics together!
I'll let the Omniture engineers figure out the details (b/c we all know they have super powers), but just to give a little pizzazz to this idea I have included a mock up of the "new" metric selector.
