TODO for V2 After release

[davideastmond]

• [x] #62
• [ ] Clean up styling and try to get a consistent style. Do we want darkmode?
• [x] Update notifications to make them more robust
• [ ] For comments, work on a feature that auto fetches and updates new comments that appear in the thread
• [x] Allow the canvas creator user to delete a whole adventure canvas
• [ ] Come up with a permissions structure to indicate the amount of read/write access permissions a invitee has on a canvas
• [x] #63
• [ ] Create user profiles, allow image uploading

I'll convert these into cards.
