You can already achieve this with labels and filters.
Settings -> Folders & Labels -> Add label -> Name it however you want the inbox to be called
Settings -> Filters -> Add filter -> Name your filter (name it whatever, it doesn't show anywhere) -> Click next -> Statement: ALL, IF (the recipient) (is exactly) [enter the email address you want associated with this label] -> Click next -> Label as [Select your label] -> Save.
Repeat this will all your addresses. You can then select which label you want to view on the menu to the left.
