Awesome! Are you able to handle sums of diagrams like (-M- + -a b-)-c etc?

Thanks! Right now, it does not.

I focus on a common case of a single product without any other parts. If there is a summation, it is managed via indices.

If you are interested in arbitrary drawings, you are probably aware of TikZ (if you like coding) or Excalidraw.
