I know there is addons that help you change the color of droped colors, because sometimes you get confused gold with unique items, additionally if possible can you change colors of droped items like grand charms, flaweless or perfect jewels. Vendors would sell perfect jewels would be great addition to this for free, saw few servers doing that.
Also it would be awesome if you could change that lets say if you press alt twice or something that items that droped always showed, so that it wouldnt require holding alt to view droped items. Downgrading runes, egzample rune + any perfect jewel = 1 lvl lower rune
