In order of how much i want it. 1. Resources and mining, make our trips to other places more usefull. Maybe let us sell the ores / make parts.. 2. Mechanical parts, robot arms on which you can attach parts like docks etc. 3. Permanently destructable ground, when you crash a big rocket you are left with a big crater. 4. Usefull electric engines (but it wouldn't be realistic so it will probably not happen).. 5. Fuel generating (maybe from solar power or nuclear power) Not sure if this would be realistic. 6. A fix for lander legs so they don't sink into the ground or some other weird behavior. 7. Sometimes i'm not able to click on the orbit to make a manoeuvre (very annoying). 8. More tollerance for docking, it has to be very precise now, i don't think that is necessary. 9. Sometimes unable to attach objects using symmetry despite the fact that nothing is in the way. (For example when you attach tanks around another tank, and no mather which one you select there's always only 1 turning green) 10. More multipliers for symetry (Why are you skipping 5 and 7? :S ) 11. Sub categories for parts, for the category Propulsion have sub-categories for Tanks and Engines. (maybe even further than that : Tanks > RCS, Solid, Liquid.) I do realise it's kinda hard to sub categorize everything since there are gray area's. 12. The right-click menu's when collecting science are not optimal in my opinion, for example : If you did an EVA report, the button still stays there, that's not necessary right?
