Yet I still noticed the spellbook changes in the beta. My racials, guild perks, and flying licenses were jumbled up in the same tab as my spell passives, talented abilities, and regular abilities. Without even a search box up, I had to flip through all the tabs multiple times to make sure I hadn't missed anything.
Ghostcrawler posted two weeks ago about the pros and cons of the new beta spellbook design. I don't quite know what four to five tabs he's talking about -- to me, everything appears to be one big mess in the same tab.
