Although this isn't a direct answer to your question, but everything that can be done in Herdr is trivially discoverable by asking a CC (or equivalent) session inside Herdr. In fact a lot of the things I do in Herdr I do by asking an agent to do it for me, instead of trying to learn how to do it manually.

Some things might require a non-trivial workaround, but a coding agent will also happily build and test it for you.
