@User Well, yes, it is just a matter of writing the cell. I'm currently working on better support for basic cells and interfaces, but a working momcap is available. Placing the momcaps in an array is trivial (there is a function for that to do it with one call), the connections between them are a little bit trickier and have to be built manually. I'm also working on providing some basic functions for connections, but right now I don't really have time for that. I also need some inspiration for that. I was thinking about something similar to how tikz specifies connections (e.g. pt1 -| pt2), which should be fairly easy to implement. If anyone has some ideas, I'm happy for suggestions.
