Please install this and all versions by unzipping in the Kerbal Space Program folder and and then let it over write the previous version, All part names are the same and shouldn't stop any previously made craft from working. These are the place anywhere doors I always wish I had. Just type door in the parts search to have them come up. It is a collection of works from TiktaalikDreamer,LinuxguruGamer,SuicidalInsanity and me ColdJ. I have adjusted and reconfigured where needed. It is not perfection but I think you may find them very handy in a wide range of builds. The files are uniquely named and will not clash with any other instances you may already have. Just unzip in the KerbalSpaceProgram folder. Now with place anywhere windows and and docking collars and sleeves. Enjoy.
