What plugin(s) can you not live without?

I recently returned to Lord of the Rings Online, and one of the first things I did after reinstalling was hunt down all the old plugins I had a couple of years ago. Some are more important than others, but one is basically indispensable.

Without TonicBars, the LotRO interface is a horrific jumble of 27,000 hotbars and 127,000 abilities, but with TonicBars these abilities are kept neatly off my screen until I roll over the appropriate button and unfurls the underlying bar. You can also configure the plugin to display a hotbar only when various gameplay conditions are met, like, say, your health dropping below a certain percentage.

So that's my indispensable add-on. What's yours?
