My idea is to be able to name your gear vaults so you can just look at it and have a good idea what you have in it. This is troublesome for me because I have been playing a very long time and have many gear vaults. Ideas may be...... The name of each school, different holidays, different attributes such as damage, resist, no stat. etc. Party, Costumes, Fun, etc.
Gem and seed vaults may have good use in the same thing.
