Some other Ethereum tokens (ERC20 tokens) can be managed using Ledger Nano S and Ledger Blue with MyEtherWallet only (it won't work with the Ledger Wallet application):
all the ERC20 tokens supported (click to see the list)
If you have an ERC20 token which is not supported by MyEtherWallet, you can access your account on MyEtherWallet and choose "Add Custom Token" with these information related to the token : Contract address, Token Symbol and its decimals.
When a new altcoin is added to the Ledger Nano S and Ledger Blue, you will only need to download the last app (free) or update the firmware.
please note, that you can install about 5 or 6 applications at the same time on a Nano S, 8 to 10 on a Blue, but you can manage all the coins above by removing and installing the applications. Removing an application won't make you lose your coins, they will still be attached to your wallet. You'll simply have to reinstall the dedicated application - a few seconds process - to manage this coin again.
