During the weekend I tried addint both starfall and Force of Nature.
I picked up the spell ID from wowhead.com and Jamba found the name itself as I recall. I had some issues setting the proc time since it reverted back to the default again and again.
When I used the spell on my toons it diden't pickup the "proc" even though its not a proc. I wanted to use the proc module to monitor the cooldown of those two spells.
I have a similar for Innervate in one of my addons which shows me a bar like Jamba.
