I have some suggestions that would massively improve the friendship system in Wizard101.
1) Oftentimes I add different wizards from the same account. We should be able to click some button that would show us the other wizards a friend has, provided that those other wizards are also on our friends list. So we wouldn't see all of the other wizards our friend has, only those that have been added to our friends list.
2) Wizards from the same account should only take up one space in our friends list.
3) We should be able to add some notes to every friend. These would be private notes that only the player can see. This would help us remember who people are and where we met them.
