SCREENSHOTS

Taken straight from the application while running.

Hadirin dashboard: present, late, absent and excused counters, an attendance trend line, absences per class, and today's sessions.
One school day: 326 of 354 student-sessions present, with the absences broken out per class.
Leave request queue with approve and reject actions, and a history table below it.
A leave request is approved once, and the status is written back across every session in its date range.
Settings screen for start time, tolerance in minutes, school year, and a holiday calendar.
The two settings everything else depends on: the tolerance minute and the holiday calendar.
