Add accounts and list

So that people can create wish-list, owned-list, watch-list, etc...

---

• Curated lists
• Author black list
• Owned list (manual)
• Several named fav lists
• Mail when an item in the favlist have a discount/price change
• Mail when an item is released by an author

Having a way to show with overlay or even to hide 'already owned' things would be amazing!
