Quick Mango request: Adjustable contrast/intensity for unselected F-Curves in

Graph Editor

Under User Preferences -> Editing, there's a new setting "F-Curve Visibility"
which controls the how much F-Curves blend in with the background colour.
Increasing this value makes F-Curves stand out more, at the expense of making it
less obvious which F-Curve is active.
