I think the new UI looks great, it’s much cleaner. I’ll have to get used to the new placement of certain things but that’s not a huge issue. Overall it looks like it will be more intuitive for new players, KSP’s UI is pretty awful for anyone unfamiliar with it, especially since most of the important stuff (staging and throttle) is delegated to hotkeys.
I don’t really care about time warp being called “time zoom” now. It doesn’t say “time zoom” anywhere in the actual UI so what does it matter what they call it behind the scenes?
I’m glad there will be a limited form of life support, I think this will be a great addition as long as it’s not too involved.
