We added bottom navigation to the class overview screen, so that you can easily switch between main, students and schedule screens.

Now if student didn't have a valid ticket at the moment of the registration to the class, you will see a red dot next to his name in the class overview.

We also added lists of classes given by each teacher to the Teacher overview screen and updated Student screen.
