This is a simple notification mod that overrides XenForo's default 'stackAlert()' function to show the actual alerts as notifications.
When you get new alerts via ajax, the function 'stackAlert()' is called to show a message like "You have 2 new alerts" at the bottom left corner of the window.
This add-on shows notification when there any unread conversation and any unread alert created by the system.
Here's a demo video of what this add-on does. Here, the page is refreshed two times, first half is to show that the notification auto closes after 10 seconds and the last half is to show that the notification can be closed by clicking the close button.
There are no options or tweaks. Just install it and have fun!
Upload everything from the 'upload' directory.
Import the add-on XML file from admin control panel.
