Well I use clique and Grid for both healing and decursing. Clique allows you to assign button clicks with no modifier, ctrl, alt, and shift. and Grid is the unitframe mod, and I would definately recommend grabbing a few of the plugins for grid such as GridStatusRaidIcons (shows you the raid lucky charns), GridIndicatorSideIcons (gives you more places to show icons) and also there is one that labels who is your main tanks but sadly I don't remember the name of it and I don't have it. But when/if you grab grid and clique don't download it right before a raid as there is a little setup involved.
Hope this helps you out!
