Needed in Photoshop: proportional leading/line height as in CSS

It’s always bothered me that I cannot effortlessly create proportional line height in Photoshop. The leading widget in the Character panel should use a multiplier of the font size—as in InDesign or CSS.

For example, I could set my text to 24px and the leading to a 1X, 1.5X, or whatever multiple of that. If I change the font size, the line height would adjust proportionally.

As of the latest Photoshop CS6 beta, this has not been implemented.
