Multiple Notification Bars

First off, great plugin. I love the simplicity and ease of this plugin.

Stupid question: Is there a way to have multiple Notification Bars displayed at once? I was imagining if you have two active Notification Bars that they would display next to each other vertically — one on top of another without overlapping. Turns out only the latest Notification Bar is displayed and the previous one is ignored.

If not stacked vertically, then how about the plugin randomly displays an active Notification Bars?

Thanks in advance!
