Not sure if you checked the Cure tab in the configuration to watch for debuffs on self/party/raid. I think that is where you set up what to watch for.

I have my tankadin set up for cleanse and the rest of the buttons are for tanky things since Healbot will show agro swaps, kinda nice to taunt off one of the team with a single mouse click. I have intervene set up on my warrior... but it really doesnt work as nice as RightDef.
