Sumary:
When adding a new assignment it is placed at the end of the list, I would like to have the option to filter them by date and/or class.

Steps to reproduce:
Create assignments with different dates and different class

Expected Result
Order by Date

Order by Class and date

Actual Result

Summary:
When we create a class and edit a field (teacher name or color) the data is saved, but there isn't a notice indicating that it was saved correctly.
A Toast, a Dialog or something similar would be nice :)

Steps to reproduce:

• Add a new class
• Fill in the data
• Save the class
• Click hamburger menu
• Go to "My classes"
• Select a class and change any value
• Click Save button

Expected Result
The information is saved and the application display a notification about it.

Actual Result
The information is saved.
