We do have another site we use internally and that is indeed how we track much of our work. But we don’t do so with any secret plugins.
Mostly, we use conventions, like a category for “todos” and a standard set of a few tags for a kind of now/next/later prioritization, along with the assign plugin to clarify ownership.
That enables the kanban theme component to work too, but not everyone uses that view.
It’s pretty fluid, not a highly opinionated issue tracker, but it works well for us.
I could share more details sometime…
