Make the hex code box visible for all color modes on the color panel. Not just RGB modes.
I only ever use HSB to dial in my color and it slows me down to double click on the color to only have to copy the hex code in a different window. The only modes that currently have a box that displays the hex code are RGB or WebsafeRGB. This is missing for all other modes such as HSB, CMYK and Grayscale. Make the hex code box visible for all color modes on the color panel, please.
