Small Issues and Patches - Question Sets

[GrifTheDev]

Any small things worth fixing go here.

• ! Since localStorage can be changed someone could put in a QSCP that contains an id for an already completed QS. On all QS creation related endpoints, add a check to see if the QS is already completed.
• Add trycatch everytime localStorage is being JSON.parse'd since it will throw an error if it is just garbalaed nonsence,
• DELETE Question Sets
• Add numbers to QSC tables.
• Add question set title length limit.
• Implement messages from server displaying on all pages.
• Add proper logging
• Loading when question sets are saved and when questions are submitted from modal
• Add types and check permissions on /api/question_sets/add_questions
• Add questions remaining on question addition flow
• Fix question block overflow bug
• Add question set titles to question creation pages
• Back button in question creation flow
