[Feature Request] Animate Chains

As a Comfy user, I would like to clearly understand which step of the flow is currently executing in the UI so I dont have to check the command window to confirm its still running. While in some cases it appears the box is outlined in green indicating its running, oftentimes I am not seeing this. Perhaps similar to chainNEr, an option to animate the chain can be implemented so its clearer what step of the process is actively running.
