Devlog 4: Added ability to add classes as well as better UI layout.

Here is a snippet of the edited portion!

  const [courses, setCourses] = useState<Course[]>(() => {
    if (typeof window !== "undefined") {
      const stored = localStorage.getItem("gc_courses");
      if (stored) return JSON.parse(stored);
    }
    // Default fallback starter course
    return [{
      id: "default-course",
      title: "Introduction to Calculus",
      gradingMode: "weighted",
      desiredGrade: 90,
      weightedCategories: [
        { id: "1", name: "Exams", weight: 50, currentScore: 85, isExpanded: false, items: [] },
        { id: "2", name: "Homework", weight: 30, currentScore: 95, isExpanded: false, items: [] },
        { id: "3", name: "Final Exam", weight: 20, currentScore: null, isExpanded: false, items: [] }
      ],
      pointsAssignments: [],
      credits: 4,
      courseLevel: "Regular"
    }];
  });```
