Post-launch Vanilla through Cata had a really messy afterthought of a format for how non-primary gear stats were displayed on items. MoP fixed this by incorporating every regular "Equip:" stat back alongside the primary stats, just colored green.
This addon hooks into tooltip and itemlink frames to try and reformat the designs to a similar clean format, which leaves the special, out of the ordinary effects their proper chance to visually stand out:
Enchantments that are simple stats, are also brought into the standardized format while retaining their distinct green coloring.
We're not at 1.0 release yet, this addon is still in dev. See the Issues tab for info on what's wrong.
