It would be nice for the Usage Statistics macro to be able to report on unique user activity in a given (configurable) time period. It would be even better if this unique activity can be extended to the entire space rather than just on a page level.
Administrators would like to be able to use the macros provided by Usage Tracking Plugin to report on unique space visitors for a given a time period. For example: "Show all unique visitors to this space within the past 30 days". This is used to gauge space activity and possibly to discover candidates for archiving unused spaces.
The plugin records every single page view, and the Usage Statistics macro does not group unique users together. For example, if a user refreshes the same page 10 times in a couple of seconds, this would be reported as 10 views
The macro does not group activity at a space level. If a user visits 10 different pages within a space, this counts as 10 different views and is not counted as "1 unique visit to the space"
