Improving passphrase support

[jmptbl]

Description

I'm evaluating a Jade wallet in conjunction with Green and BIP39 passphrases. The UI implementation needs improvement.

Firstly, with logging into a wallet it takes some time to enter the pin and passphrase on the Jade. While the user is doing that, Green starts reporting that the Jade must be reconnected, or that timeouts occurred. Once the user has finished, Green often gets stuck or loops back to requiring a pin code entry again. Reconnecting the Jade doesn't seem to help. All of my testing has been via a USB connection.

Secondly, after the wallet is setup and accessed from Green, the experience of accessing the wallet with a different passphrase is quite problematic. In addition to the connection and timeout errors described above, Green flashes an error so quickly that it's barely readable, which states that the wallet hash has changed. Obviously the wallet hash has changed, that's the whole point of having passphrases. To get a second passphrase working, one has to tell Green to create a new wallet. But then the existence of two hardware wallets is displayed in Green, which defeats the discretion of passphrases, and one has to remember which wallet uses which passphrase.

Please can these passphrase usability issues be worked on?

Additionally, in Green there seems to be no way of displaying the wallet hash. Somewhere it would be good if the wallet hash is displayed. It'd be great if the wallet's derivation path could also be seen somewhere.
