Hi,
based on some discussions that happened on the ProtoPioneers platform, I think it could be useful to add comments to triggers and responses to help the prototypers understand older pies, other's pies, and in general how the functionality works.
In coding, we can write comment sections and single comment lines directly to the snippets and in-between the code (green texts), which makes it super understandable and connected. I like the markdown documentation in ProtoPie, that we already have for components. I wish we could use it for triggers and responses as well.
