Would it be terribly difficult to possibly stick some additional filtering options on the Player activity graph?
I think most of can take it for a given that useage numbers on weekends are going to be significantly higher than those found on weekdays. Once enough of a data spread is avail, it would be kind of interesting to take a look at how those numbers actually play out.
I would love to be able to separate weekday from weekend, but there is no reliable way to do so. I can do a 'soft' filter based solely on when the data was entered on the site, but it would be no guarantee as to which date the data was actually collected.
