Eyedropper in Color Picker dialogs

There is no way to "eyedrop" colors fr om the image (or filter) you're working on

Please add a simple eyedropper that is active when a color picker dialog is open, which allow you to "pick" any color fr om the screen/interface.

This is a very basic feature that is easy to implement: when a color dialog is open, if the user clicks anywhere on the screen except inside the color dialog interface, sample the pixel and show that color in the picker.

The feature has been requested numerous times, here are some of the requests:

Say, at the moment I'm using a Chroma Key filter to remove coloured backgrounds from an image. If I could click on my colour control and then when the color picker was open just click somewh ere within my image, I'd be able to work much, much faster. Maybe this is something that's already planned for FF3?? (source)

I'll use the watercolor frame by Kochubey as an example. The color of the frame can be changed by clicking on the frame color box under the settings tab. But if I want that color to match a specific color in my photo (jpg)I have to eyeball a similar match. (source)

n.b. I am aware of the eye dropper tool inside the editor. This request is primarily about making the functionality available wh ere it is needed: front-end (i.e. not the editor) and when actually selecting colors (the editor eyedropper approach is somewhat unhandy workflow-wise)

"Everywhere" is definitely the nice option - then it will work like in Photoshop: when a color picker dialog is open and you click and hold down the button, you can "eyedrop" anywhere. Ofcourse the eyedrop cursor is only active inside the Photoshop interface, but if you hold down the button and move outside the Photoshop interface you can sample from any application on any screen
