In the assessment tool the coach can start a configured assessment mode. Specially for manual assessment mode configurations (but also for automatic) it is very useful to know how many of the students are already logged in and waiting for the assessment to start.
The idea is to show this information to the coach.
The same information should also be added to the assessment mode list in the assessment mode config tool.
Once the assessment started, the message could be changed to something like
"45 von maximal 65 Teilnehmer nehmen aktuell an der Prüfung teil".
The feature is a usability improvement. If technically to complex because the count of waiting users in the assessment mode is not possible to get without major refactoring, the implementation will be rescheduled.
