Add Action to Tools menu
I tried to add an Action to the Tools menu. In the MPS 3.0 documentation there is a reference to Tutorial: how to add an Action to the Jetbrains MetaProgramming-System. I followed all the steps in the tutorial (slightly adapted because I use MPS 3.0, the tutorial is 2.0)., Everything goes fine, it seems simple enough. However \the new action never shows up in the Tools menu. Is the tutorial out of date? Or do I need to do something additional to get the action to show up?
