Perform usability testing
Large Effort task
The front-end has not been tested well enough and would benefit from having more students test it out and give feedback.
I recommend coming up with some expected use-cases and then ask students to complete those tasks without assistance. See what they struggle with and get their feedback on what is confusing and what they would like differently.
Potentially come up with some prototypes of different designs, it doesn't have to look the way it does currently.
