Just as an FYI, you may want to add a note about installation to readme.html. it functions great as a changelog as of right now, but with spaceport closing down and it always being a good idea to include instructions, you may want to include something like "unzip download and put "EditorExtensions" folder into KSP gamedata a folder." Most modders will realize this, but some newbies may not. I would branch and merge, but I'm not sure with such a small issue it is reasonable to do that.
BTW, thanks for the great extension.
