With enough patience you could get grid to look almost the same. I just don't use grid on any of my dps toons (which is basically ALL of them, lol) as I don't need or want all the additional shit.
I rebuilt the UI, v3.0 now available on wowinterface.
Anyone using my previous versions will want to update asap. I identified a problem with the old PowerAuras layouts that was causing a massive memory leak and severely degrading performance. I believe it was bad enough to cause chain disconnects and other odd behavior. The issue has been resolved and everything is running smoothly.
The ui is strictly customized for 1680x1050 displays, though it may function with other resolutions.
These two files need to be deleted from the SavenVariables folder on ALL of you toons (WTF/Account/accountname/Server/charname/SavedVariables), as well as WTF/Account/accountname/SavedVariables/.
You'll also need to delete the PowerAuras folder from your Interface/Addons folder.
Once you have removed those files/directories:
If you dont want to set up the auras again, you can download the UI and copy the PowerAuras folder to your Addons directory. You'll also need to copy PowerAuras.lua, PowerAuras.lua.bak from the UI back to WTF/Account/accountname/SavedVariables/ and WTF/Account/accountname/Server/charname/SavedVariables
Some of the settings from the old UI didnt make it in to the new one, but if there was a particular aura you wanted, that isn't included, just let me know which ones and I'll copy the import code for you.
