Attempts to implement notifications similar to those available in Ubuntu since Jaunty Jackalope (9.04). This plugin presents notifications as "ephemeral overlays, which can be clicked through so they don't block your work".
For more information, see the following:
Click on the buttons below to create some example notifications
You should be able to hover over the notifications, at which point they should become transparent, and the cursor will change to reflect the styles for the elements below it. Clicking on an element beneath a notification should trigger the click event for that element.
For now, please get the source code from GitHub.
