Thank you very much

Hi KSP Community, Today I scrolled down the KSP Facebook site and they posted a link to their Twitch site. I watched some of the Videos they had there and saw a very useful mod in this Video at 0:45 sec -> http://www.twitch.tv/ksptv/c/5516992 Does somebody know the name of this modification? I searched for every possibility this mod could be called/described by but I didn't find anything like what I saw. Sorry for my bad english, it's not my native language. Greetings, BdBY
