As shown, there is a problem in core/index.js ext function:

@Download I think this doesn't work since it seems to be a problem with the ext core function in notify 🤨

The problem is, that this function calls itself with every logger instance. So it would be better to do the logger ext call asynchronous.

core/index.js:33

for (logger in ulog()) {
	window.setTimeout(function updateLogger() {
              ulog.ext(ulog(logger))
	}, 0);
}

As example with more than 20 ulog instances:

Mmmm I think I like this idea!
Thank you thank you for your enthusiasm @Messj1 !!
I will review and merge this asap

Ok so I did not merge this. Sorry.
The reason is that I noticed that there is a real perf issue, only when you change config and have many loggers.
With a thousand loggers it takes 4 - 8 seconds! That's way too long.

It's better to fix the real perf issue than to hide it behind setTimeout I think.

I have some ideas on how to tackle it but it might make the API for mods (even) more messy.... Then I got a new job and got totally swamped with work and stopped working on this for a while.
But I will get back to this. Eventually. You are not forgotten.
