AliasVault: Open-Source E2EE Password & (Email) Alias Manager

I’ve been using it for almost a year and I love it! Is there any way I can mass select login/alias to move them to a folder in bulk? And I have a question regarding the email in AliasVault. I’m currently using the domain @aliasvault.net exclusively. Is it correct that if someone enter the same email address I’ve used, they will be able to access the mails? For example, if I created unseen@aliasvault.net, can someone use the same email address unseen@aliasvault in their AliasVault account?
