We ship Chromium and the Plasma Browser extension and using web services like Messenger or WhatsApp sends notifications to Plasma which means that the notification applet is blastered with notifications. Currently to clear notifications the user has to click on each individual notification. This is fine when there's only a couple but it's a chore when there's too many.

So we need a simpler way to clear all notifications from the applet.

As described in the title

Steps to reproduce the behavior:

1. Click on NX Notifications widget on the panel.
2. Click on "Configure Event Notifications and Actions" button
3. No configuration window opened

It's supposed to open the Notifications KCM.

After installing it I can find the Nomad Notifications in the systray of a Latte panel. When the user changes its layout from e.g. Plasma to Unity, Latte Dock app crashes. This isnt happening with the plasma notifications. If I disable the Nomad notifications in that systray then everything works fine without any crashes.
