It would be awesome to have the following features that are extremely easy to implement:

• "Farmable" selection box (similar to the "Vault" selection box) for sorting (in vault, in champions, etc.)
• Search bar and/or "duplicates" check box for finding champions quicker - it gets a bit ridiculous once we have hundreds of champions and start saving duplicates and them not showing up together)
• Be able to view armor in the vault (currently it is only the initial one selected) which would really help when finding the champions that are currently being worked on for faction wars teams, etc.
• A new screen that would allow building default champion teams for each area
