Canadian ROM goodness for US At&t i747 users.
The ROM's name is simply "i747z", in reference to that one letter of the alphabet that differentiates Canadians from Americans. Each will pronounce the name of this ROM differently. Plus, I wanted something simple and stock-like on /Settings/About device for the phone for those who might have company IT Departments viewing their devices. Having something like "Frankenstein's Butthole ROM" on the device kind of gives away your rooted status a bit more. BTW, you may refer to this ROM by the above name, if you like.
The current Jelly Bean 4.3 from Samsung is pretty solid. But, as we all know, for whatever reasons, At&t will take a good ROM and add restrictions and "features" that make it barely usuable.
Our Canadian GSIII brothers, on the otherhand, are usually, mercifully, spared from the full carrier hack-job given to us by At&t.
Luckily Samsung is kind enough to hide the as yet unreleased Canadian carrier ROM features in our at&t UCUEMJ2 leak. Using these ROM features, I have attempted to give us in the US what At&t should have.
This ROM is odexed (re-odexed), as it would come from Samsung. In theory, this should give you better speed and battery performance. I have found it be lightning fast, smooth as silk, with best I've tested battery usage. Let me know what you think.

-Precise battery mod. (This is what I call my 1% battery mod. There are no percentages on the battery, itself. IMO, not necessary since the option to display remaining battery percentage is available to us in a stock ROM. So, whereas in a stock ROM, the battery image displayed in the status bar will change only after 10-15% is lost or gained. With my theme, the blue or green in the battery image will gain or lose one row of pixels for every 3-4% lost or gained. Even without battery percentages shown, in a day or 2 you will be able to guesstimate how much battery you have left within 5%, in my experience.) Thanks to Wanam and Lidroid

Reodexing .jar files is proving to be quite a challenge on TouchWiz 4.3. So, at this point, to enable the features you need that I have not been able to yet include, I would recommend you install the great Xposed Mod from here...
...and also Wanam's great Xposed mod from Google Play
