Behaviour: In the course view, there’s a usability issue with the green “+” button. When hovering over it, the icon unexpectedly transforms into a red trash can, indicating a delete action. This behavior is both semantically confusing and potentially dangerous as it could easily lead to accidental deletions, especially if users intend to click “+” but misfire due to the icon swap.

Desired behaviour: Maintain consistent semantics: If the button is meant to delete, it should always display a delete icon.

Alternatively, separate the “add” and “delete” actions into distinct buttons to avoid ambiguity.
