In the same time I added a class .has-icon to add paddind to .sn-title & .sn-content only if the notification has an icon

Can you please resolve any conflicts, it looks like some of the additions you made were included in a previous fork as well.

any update on this issue? This and "No clickIcon EventEmitter on Notification #282" seems to be related and I am stuck on this issue too. I tried to use following option overrides:
clickToClose: false,
clickIconToClose: true

but nothing happened. Then I tried to use the notification HTML method. It successfully made icon hover effect but it would throw "emitter" error.

I am looking at "ngx-toastr" as an alternative if this one doesn't work out. It has almost all features, except that global settings are only available in "forRoot" method.

Woah. It should be noted in README that this project is not maintained. This is a 3 years old issue, and there are plenty more old ones.
