The kind of function on page 97/418 of the Macintosh human interface guidelines.
Clearly show which software is in use and which software is notifying.

Currently we have implemented a notification (yellow exclamation mark in the Windows menu) if a window that is not the frontmost window requires attention, but we have not yet implemented something to see from the Windows menu which application/window requested the attention.
Something still needs to be implemented to address this. Code contributions welcome.
I have one more thing, that is you removed some software in the window list, so how to notify the user if there is an error or completion in the background
