I can't think of any, AFAIK we have the logs panel in all these dashboards already. We'll probably need to figure out how to pass custom markdown to these dashboards, like for playbooks etc., but that can happen in a future PR.

...Or it can happen in this PR, if we have ideas about how that should work. 😆

Deferring this for now. If we want it we can resurrect.
