To Do

There is still plenty of space for improvements. Those include:

• Add ability to sign up
• Add ability to share collections
• Improve database helpers (e.g. hide one-to-many relation between collections and links from the outside)
• Enhance offline mode
  • Show cached content while initial request is pending
• Implement refresh tokens (requires backend changes)
• Add tests
• Clean up code
