I would still prefer that banner notifications not auto -hide -remove at all, as it hinders multi-tasking.

Edit: Also, you shouldn't call it "auto-hide" when you're not hiding the message; you're removing it from the DOM.

If you were simply hiding it with CSS, then I could simply override it in my personal CSS.
