They have been working on the dashboards a fair amount recently but if you’re expecting a brand new look, that isn’t likely to happen. They recently hired the guy behind “bubble cards”, who has then put a lot of work into the stock UI’s tile card. It’s pretty obvious this is the direction they intend to continue.
However it’s very extendable with themes and there is even some project that uses some entire closed source frontend for their dashboards. I forget the name of it though, but it might be worth looking into for you.
