I have one problem with the settings for Secondary Splash though. In the video you posted it seems like the icon for the spell coming off cooldown flashes and then disappears. But when I activate Secondary Splash the icon stays there until it’s replaced by a new spell coming off cooldown. How do I get it to fade out after 1-2 seconds?

You won’t see that sort of feature on any addon these days. Any sort of dynamic list isn’t clickable in anyway. Blizzard broke this to get rid of the original Decursive and the first Healbot, among other things.

Just to add to what Aryas was saying. It could perhaps do with a ‘clique’ compatibility. For instance, if you were a renew spamming holy priest, you could use the ‘buff bars’ to track your renews, but ‘clique’ the bars to apply another renew to that selected raid member.
Hope that made sense. I do find it very difficult myself to track a player via the bars and then find them via raid frames to recast. It’s not very intuitive.

However, I still agree that Forte is an excellent add-on and I recommend it to anyone for tracking cool-downs, the ‘cool-down-bar’ is just a fantastic visualization for doing so.

Maybe we have our grid set up differently, but on mine, my top left is renew with a timer (and a green –> yellow @ 3s –> red @ 1s colour change). I couldn’t imagine looking at a renew listing and trying to quickly find the correct name in grid all the while making sure you’re not standing in fire.
