Message Cache
The adv-growl-module now internally uses a message cache. This cache gives you the possibility to limit the number of messages displayed on screen. You can control the number of displayed messages on screen with the "messageSpots" property. Simply pass a number that indicates how many messages will be displayed on screen. This feature is very useful in combination with the life property. The combination of messageCache, messageSpot and lifeTime will cache messages that can not be displayed due to missing message spots. Those cached messages will appear as soon as a spot is available.
By default this property is set to 0. This means that you can create as many messages as you want
