Thanks! The tutorials on the Modelica-like features of ModelingToolkit.jl are just starting to roll out. For example: https://mtk.sciml.ai/dev/tutorials/acausal_components/ . Indeed, there's a lot to do in this space, but we already have some pretty big improvements that we'll start writing down and share (hopefully) at JuliaCon 2021!
