I just added this module to ModularGrid:

I found the discussion on MW where it's getting a lot of interest. The developer is really listening to what people have to say. For example, some found issue with the connectors at the bottom on a controller. The developer decided to implement an upside-down usage mode. Consider me interested as well!
