It's time to fix the Curves adjustment layer

Many Photoshop users consider the Curves panel to be Photoshop's most important feature. For many Curves users, the Layer panel introduced in CS4 does not offer the speed, the instinctive use, nor the superior results of the older Curves Layer panel. The Curves dialog includes all the features that long-time users rely on. Some of these features have not been included in the Adjustment Layer version. They should all be available in the Layers panel, too.
