School term based overview about groups (not only via printout) [or: Reconception of "My students"]

This overview should display the following data in a table:

• Students name (linked to students overview)
• Students primary group
• Absence, tardiness and extra mark statistics

There should be also an easy way to get the printout and the week view from this view.

The table should be grouped by groups, beginning with groups without child groups.

This was several mentioned by teachers.
