How to set node attributes to node or panel ?

[JuhaW]

For example Color Correction node which works for gpu also, Brightness, Contrast and Saturation values are currently in Node Editor (N) panel and I want them inside node for easier manipulation. How to do that ?

I do hope there's some cleanup with some of these common nodes where you have redundant places to edit values. Ideally you'd be able to have the values in both, and that they're connected.
