Is there a way to custom the icon showing in notification?
The message does not wrap but cut off if longer than the width, any workaround?

Icon is dependent on the script icon. Just found that out myself.

I am getting this error:

  % python3 mlnotifications.py                                                                                                                         !10244
Traceback (most recent call last):
  File "mlnotifications.py", line 1, in <module>
    import Foundation
ImportError: No module named 'Foundation'

Should I install pyobjc?.

Is it possible to set a callback? For example, when a button is pressed, open a URL
