Theming and stacking for panel notifications

It would be nice to have a theme option for panel notifications of type success, i.e. “negative”, “positive”, “warning”, “info”, “none” (like the info field or the k-stat component), and to be able to stack multiple notifications on top of each other (like this vue toast).
At the moment, only one notification can be displayed at a time.
Thank You!

this.$panel.notification.open({
    type: 'success',
    theme: 'warning',
    icon: '⚠️',
    message: 'Be warned, You're about to listen to Helene Fischer!' ,
    timeout: 2000
})
