Sorry to ask an Off Topic question but which version of CM10.1 are you running- I cannot find any later than 18.11.2013.?
Latest version is 20140112.
You can install what you want and update it from "Updates" in the menu. Or go to http://download.cyanogenmod.org/ and find your device (p4 e.g.)
Ok. Enough off-topic.
I din't start to use Omni on my beloved p4, only on my mako. Just waiting a little bit, it need it for my work
