The option to separate the alerts during editing, so that different alerts can come up in different areas of the screen, while also keeping the current editing option for those that need all of their alerts editing in one place! Especially as I also would like to keep some alerts up for longer than others.

Also,it would be good to have a border around my alert that shows up once the alert happens; not a border that stays on my screen permanently, whether an alert is taking place or not. As well as the option to animate the alerts too!
