Option for RGB Readout that floats with cursor

I would like the option to enable a constant readout of the RGB values under the cursor, that floats along next to the cursor at all times. Too often I find that these values, which appear at the top of the stack of editing functions, is offscreen, requiring me to move off the part of the image of interest, adjust the editing stack so that I can visualize the RGB values, and then return to image.

I have customized my workspace so that the histogram is in the left dock. Check out the how-to here: https://help-photolab3.dxo.com/en/general-interface$Managing%20palettes%20and%20workspace
