Create new accounts on the fly

[durbanpoison]

I would like to have the ability to create new accounts in my wallet on the fly, even if none have ever been used. I would like to be able to give out unique addresses to people and not have to wait until one of the addresses is used before I can generate another address. Additionally, for privacy reasons, I would like these addresses to be in different accounts so that their UTXOs are not unintentionally merged as inputs in a new transaction.

I have used wallet before where I could generate addresses on the fly and this would be a really helpful feature to have in Ledger, especially if I could actually generate unique HD accounts on the fly.
