It would be nice to be able to copy the hex values on existing color styles from the top level, for pasting the hex values on a swatch, versus having to click deep into the color style for it. Maybe even a simple right click on the color style in the Design panel?
In addition, maybe an item with that color style applied could have a copy hex option?
It would make this already monotonous task a little bit faster, easier, and less error-prone.
