Knobs for resetting state / tuning on history / displaying data

:+1: great idea ;-)

Start with example_src/devdemos/defcard_api.cljs at lines 374-377 and review the referenced card heading panel context. The issue proposes controls for resetting state, enabling history, and displaying atom data, but does not define their behavior, scope, or acceptance criteria; clarify those requirements before identifying implementation files and tests.
