This pattern can be found when using the Rabby wallet. If users also use MetaMask or other crypto wallets, they can click the "Flip" button to set Rabby Wallet as their default choice. This allows them to access all dapps that MetaMask supports. This feature is handy because when a new wallet is installed, it sometimes takes over automatically as the default wallet without prompting the user. This can be frustrating, but this pattern gives users control over which wallet should be the default one.
