Option for Dropbox Vault to be hidden and additional step for resetting Vault's pass-code

I think it would be a great idea for security purposes that the vault has an option to be hidden or just not so easy to find in the case someone else has access to your Dropbox. Additionally, I believe resetting the password/passcode for the vault should be a two or more step process that triggers an email that requires confirmation as a first step. The second step could be a personal security question or something along those lines to ensure privacy to the owner.
