Custom domain + email alias directly on ProtonPass/ProtonMail
It would be great if we could create email aliases using our custom domain directly through ProtonPass. I know this can be done via SimpleLogin, but thinking about a family plan where a spouse or children would use the service, it's complicated to deal with privacy education by asking them to use one portal to create emails and another to create and manage passwords and logins. Even for personal use, it's much simpler and faster to create aliases through ProtonPass directly via the app or extension.
Along with this, it would also be great if each family member could create their own aliases on their accounts using the custom domain of the family owner and each receive their emails related to their created aliases.
