Hi guys I just flashed this. Loving it so far.
Have some questions/concerns though:

1. Why can't I update the stock Calendar app to the newer one, rather I have to install the newer one (blue icon) as a separate app? Right now I just disabled the stock (green icon) Calendar app which I guess is fine, but was just curious.

2. In my SD card, can I delete "data.ext4.tar" and "system.ext4.tar" - they are taking up about 750MB and it would be nice to free it up. I do have naother folder which is titled as a date, and I believe contains the backup image, so I am leaving that alone. The above 2 files are listed separately though.

3. Is it possible to have vibrate on touch when sliding the unlock button on the lock screen? A feature from 4.1.2 that I miss.

Other than that..everything is great! Favourite features: Back button flashlight from home screen, Expandable volume control, pop-up text message display, and slide to left on lock screen (I have a Notes app there for quick notes). Thanks.
