LF Addon - to visually mark all items with small icon by expansion - For example Frozen Orb - WotlK icon
There is such for future versions https://www.curseforge.com/wow/addons/sorted (for Retail Classic Wotlk too - but it doesn't work)
This is https://imgur.com/ssrguDc image from the addon above - you can see the idea visually
