Macos: display windows and discover new windows

Question

I would like to have a list of windows, which is pretty simple, but I need also:

• A notification will be sent when a new window appears

• will be notified when an existing window disappears

• detects when window position / size changes

Do you have any ideas for this?

Thanks in advance
