Notific8 is a notification plug-in inspired by the notifications introduced in Windows 8 with some web ready restyling and customizations. Notific8 has built in themes and is easy to create new themes for. The plug-in was born from a want for a simply designed yet modern and stylish notification system. The plug-in is also designed to scale based on the page's font-size setting (it was designed for the default of 100%/16px as the default).

Often it is not enough to indicate this events only visually to get user attention. You need sounds! This library, made for playing small sounds, will help you with this task.
