My lovely new quick alerts

The 'quick alert' feature on my website is used for various different things in order to inform the users of my website of an update to the page or a successful save for example. It's been quite nice to have and I use them regularly across the website, for example when executing code in ZPE/YASS or evaluating JavaScript, a quick alert popups to tell you that the action has been issued.

But now, after a good few years of them. I've decided to make some serious improvements to them.
