And maybe also support "Target control info" in mapping panel without explicitly activating target logging.

Same with the "matched" indicator.

All of that could be achieved by syncing to the real-time processor if a UI is open or not. If yes, the real-time processor could send some messages to the main processor which then takes care of that.
