I have a 2of3 account on Greenaddress.it On settings I see this message:
(NOTE: instant transactions are not available for these accounts because GreenAddress can't protect them from double spending)
I installed greenBits and selected my 2of3 account. Go to send tab and I still see the instant transaction checkbox for 2of3 account.
I think for 2of3 accounts the checkbox should be hidden.

What do you think?
