The latest patch to the Cataclysm beta has finally added in the revamped glyph UI, sporting the newly implemented Prime Glyphs, a selection window and awesome new convenience features. The new interface has a search box for quickly finding glyphs, expanding categories of prime, major and minor glyphs, and it even shows you what glyphs you have not yet learned.
Personally, I think that the new glyph interface is one of the coolest Cataclysm revamps. The old system of glyphs was an awesome first step, but it has been refined and polished in ways we never could have expected. Check out the gallery of shots below to see what the glyph UI looks like while empty, sporting some glyphs and using the search feature.
