Great, I'm happy to see a change for this. Personally, in the non-expended view, I'd have even less information for a cleaner UI look - possibly just the very basic information like weather it has life, temperature, radius, class, and name. Then clicking the expand button would show all the other info.
On another unrelated note, anyone who hasn't seen the latest blog post
should - very exciting stuff! The new nebulae are looking better and better, SpaceEngineer has been doing a lot more work with planet classifications and making the engine very scientifically accurate, and Duke even mentioned that he's started experimenting with better water, clouds, and star surfaces! All extremely exciting stuff, can't wait for this update.
