One thing I've really missed here in this nearly perfect ROM was alarm clock app coming with 4.2.2, so... I've spent some time and here's flashable zip with it, for those who want it (for Android 4.1.x devices, only - don't try applying it to older versions):
It's based on 4.2 zip by gnufabio, just replaced apk with one retrieved from Galaxy Nexus 4.2.2 factory image (learned some basics about simg2img, baksmali, and smali in the process - apk+odex version didn't work). Original apk coming with 4.2 by gnufabio had broken countdown layout when displayed on our WVGA Blade screen (last digit was cut).
1. Clear old clock app data: Settings -> Apps -> All -> Clock -> Clear data.
2. Use root explorer app (ES File Explorer worked for me) and remove (backup first) old clock app (it comes as system/app/DeskClock.apk in CM10).
3. Reboot to recovery, flash the zip, reboot.
Tested on my own Blade with CM10, but it may work with any other Android 4.1.x device, too - no native code or Blade-specific changes inside.
