Really nice-looking revamps! Also will miss the old appearances.
Very excited with the built-in delta-v tool.
I have an idea/suggestion about the delta-v feature. Is that possible to add a function of recording the amount of delta-v spent as game/user's data? For example, recording the delta-v used to achieve a low-Kerbin orbit (80km) for overall launches or in recent 10 launches. It also can be delta-v amount used for landing or transferring to a celestial body.
With this feature, players may be able to explore and create their own delta-v map easily.
