I am running MPS 3.3.5 build 143.1301 running on OS X El Capitan. I just installed it and tried to run the robot_Kaja sample. When I run the program in the sandbox the program works fine, but the projectional editor is missing several features, like intellisense, extract method, extract variable, etc. When I type option-enter, shift-option-enter, or command-enter, intellisense doesn't appear at all. When I right click on two or more statements (like the part in the tutorial where you refactor turnAround and turnLeft into a method), the only refactoring available is "Move Node". What should I do to get these features?
