I would love a feature where the menu bar icon starts blinking or pulsating when the CPU temperature exceeds an user-defined threshold - for example when my mac is idle and one Safari tab goes crazy, the idling temp goes few degrees above the idle baseline; not at all a serious thermal issue, but nonetheless a resource waster.
Since temperature increase is one of the first immediate effect, this would provide a more immediate and noticeable warning than just the static color change.
Implementation Suggestion:
For macOS Sonoma+: Use NSSymbolEffect (like .pulse) for a native animation.
For older versions: Use an NSTimer to toggle the visibility of the NSStatusItem icon.
Thank you
