Things are up in the air... We're not getting any feedback on the progress of the new electrum-dash client. I assume that's because they're hard at work, not wasting time hand-holding on a forum.
But, some kind of hint would be nice now and again...
I use it in conjunction with my Trezor and @chaeplin's dashmnb goodness with no problems. I have a keepkey, but I haven't tried it yet.
I don't use electrum-dash's own on-system wallets, but there appears to have been some drama with that lately. I don't know if it's been resolved or not.
