Make the Color Legend Editor stand on it's own.
The Color Legend Editor hangs off the Color Map Editor. (It's the little color legend icon with an e at the top of the Color Map Editor). This is totally wrong. Please make it equal to the Color Map Editor. In other words, remove it's icon from the Color Map Editor. Add it's icon to the tool bars just to the right of the Color Map Editor icon. Add it to the View menu as it's own view. Give it the same properties as the Color Map Editor., making it dockable. As with the Color Map Editor, make it non-modal. Ask @cory.quammen for specific ideas.
