SCT and Spell Alert SCT wasnt working as good as I wanted it to so I have created an addon to add to the features of SCT. You can create patterns for events that will allow this addon to display a more prominent alert (visual and audible).

This addon is a work in progress and takes a small bit of learning to get it working (read the Readme.txt file first if you want to use this addon - configuring it will take some time).

PS. I recommend running it with all options turned off to minimize lag while in combat (definately dont use this addon for arena matches until its stable - Ill add an arena mode soon which will bypass a lot of filtering to make it usable in heavy combat situations). Also, run '/cal delete known' to clear the collected events table if collecting events is causing lag.
