Myetherwallet is only for ETH and ERC20 Tokens. For other coins (must be supported by Ledger already) then you need to download the
Ledger Manager and here is a
step by step tutorial on how to add Litecoin (applies for other coins).
Great, thanks

I'll have a look! I was trying to avoid using the ledger Apps hence the MyEtherWallet use on ETh/ERC20 Tokens, I was hoping for a similar online application like MEW that takes all other coins (If one exists) and then I would use MEW for ETH/Tokens and another one for BTC, LTC etc.
The reason being that I can leave the Ledger in 'Browser Supported, Yes' if you know what I mean, for some reason I don't want to use the Ledger wallets provided within the Ledger app.
Thanks anyway!!
Best regards
