Optimization and Usability Enhancements of the Application U2L

The web application u2l - a system for the management of tutorials for both students and lecturers, which has already been used in multiple courses - should be extended and improved. The main focus of this thesis is the improvement of the user interface. Therefore, popular views and functions are unified in order to enable the users of the system to use the system more efficiently. Additionally, a PHP interface for plugins is developed, which provides the possibility of an easy extension of the system. Furthermore some additional functionality like a grading system and a clearly structured code are also part of this bachelor thesis.
