I have asked for this for years, and since you bombard me with requests to subscribe, I'll tell you what it would take.
It's simple. The filtering available on my activities is rudimentary. I should be able to select 1 or more activity types, date ranges etc. and get totals and counts where they make sense.
I will never subscribe until you provide this simple enhancement. As a web designer/developer, I would think this would have been provided at first release. Showing tabular data with no proper filtering and reporting is just unacceptable.
