Generally, when you change the colors of some element of your design, you already have a color palette at hand that you have created or you simply add a new element that is close to another with the same color that you want to use, then you have to enter the color picker to be able to find the eyedropper there and then select it and go to the color you wanted and copy it. This slows down the process a bit because you always have to go there to copy it.
I propose that this be added together with the color code and opacity so that it is more accessible and you can directly hit the eyedropper without having to enter the color picker to select it.
