Custom lists creation by users


Hey. I am just a regular user. I would like to suggest something. It would be great if twitter team could allow us users to create personal custom lists of the people or stuff we follow so that instead of browsing through so many tweets serially , we can just select which ever list we want to. For example, I can add all the celebrities names to one list and all the technology blogs to other and so on. And whenever i feel like following celebs, i can select the celeb list or any other list for that matter. Thanks
