i believe that a new filter for the statistics (sessions, incame) should be made available.
the given filters are fine so far, but as the netcafe emplyees work in different shifts, it's rather hard to determine the amount of money each have to deliver at the end of their shifts.
so, a new general filter is in order.
this should filter the statistic (all of them) by the user that was logged into the cybera server.
so, if i want to check the amount of money that one specific employee made today(/this week/this month/a specific time table) i would simply check the new filter and select from a pull-down menu the user i targeted.
simple and efficient.
i also would not go through so much trouble to do the income, as my employees work in 12-hours shifts and they change shifths at 9 AM/PM, while the reports came based on a 24 hours interval, starting at 0:00 AM.
