I don't love the default eclipse bar, or the fact that it is anchored to the player frame. Are there any addons (preferably standalone, not a full unitframe replacement) that simplify things and/or allow for more customization?
In an ideal world, what I'd love, is a simple icon. It's a wrath icon if it's time to cast wrath (either in solar eclipse, or working toward lunar), and a starfire icon when you should cast starfire (vice versa). The icon is bold when you are in eclipse, just like the icon in your command bar. Other than that, the icon fills like a "cooldown pie" letting you know how soon the spell switch (the next eclipse) is coming. When the icon's "cooldown pie" is full, the icon changes, and you've just hit the other eclipse. I'd park that bad boy right below my castbar and be the happiest guy in the world.
Anyway, whatever exists and people recommend, I'd love to take a look at it
