When being asked to sign a message, the frame window shows the domain and the message itself, but not the hash of the domain/message. When singing with hardware wallets like trezor, the device will only ask you to confirm that the domain/message hash match what you see on screen, but there's no way to verify that quickly without calculating it itself. I would like the signing window to include two additional fields listing the message and domain hash below the data itself so that its easy to match up what you see on your hardware device with what you see on screen
