If you log in to Amazon Web Services using SAML and have many accounts, the role selection page can quickly become long, with many accounts and roles. And why should that page be cluttered with accounts you rarely use?
This addon restructures the sign-in role selection page into a multi-column design, so that you can see more accounts and roles at first glance. Additionally, you can select a subset of favourite accounts, which will be displayed first and in any order you want, while collapsing the others (but you can still expand them anytime you need to access them).
Note that this addon is in no way affiliated with Amazon.
