oGlow is an addon that adds colored rarity borders to item icons on various frames across the UI.

This vanilla WoW version of oGlow has the full functionality of the TBC and WotLK versions plus added support for the loot frame.

The options menu, which is brought up by typing /oglow allows to enable/disable what frames the addon applies its colored rarity borders to, change what rarity borders are applied from and set custom rarity colors.

While there are no Artifact items that the player can normally obtain in vanilla WoW, support for them has been added. Might be useful if your server makes use of such items.

oGlow should work with most other addons. Only "issue" that comes to mind is related to bag addons. Most bag addons nowadays come with their own rarity borders for items and oGlow won't interfere with that, it will just handle adding its rarity borders to all other remaining frames.
