I've put another update on WoWInterface. This one has some nice new bells and whistles, and I was able to incorporate some of the crucial addons that were missing. We have our trade skill window back now, and I've included a new auction addon, Auctionator. I like it so far.
I've also switched to Deus Vox Encounters after having it recommended to me by a few people. I like it so far. If you miss BigWigs, you can obviously download it from curse.
I've also written a new addon, just submitted to wowace, that is included with the new version. If you're a Boomkin, Paladin, or Warlock you'll notice it right away. :) I'll post links to my addons (I've written three now!) once this one's been approved.
You can find the new UI here, as usual.
Enjoy with your favorite frosty beverage.
