It would be great to have a to-do list in the system. This should consist of
  • Due date
  • Todo lyrics
  • Responsible employee (optional)
  • customer (optional)
  • Treatment (optional)
  • Subscription (optional)
  • Product (s) (multiple, optional)
The todo list should be connected to a reminder service that pops up whenever the user logs on to the system on or after the due date (without responsible employees for all employees)
