Wired, first time I was notified of somone's fresh topic though I had no any posts in and wasn't mentioned 😕

Now I'm going to sleep so I can't help, however I may give links to only 2 scripts I wrote that use notifiers.

I didn't do anything with notifiers from that time at all, anyway maybe that will be helpful:

Brush Rename Event  and Getting the name of the current brush preset

app.notifiersEnabled = true;  
app.notifiers.add("Mk  ", new File("~/Documents/event.jsx"), "Chnl");  

// event.jsx

if (arguments[0].hasKey(charIDToTypeID("Usng")))
    {
    if (arguments[0].getEnumerationValue(charIDToTypeID("Usng")) == charIDToTypeID("HdAl"))
        {
        alert("Bingo!");
        // your main code here
        }
    }
