I'm running Nightly Omni Rom 4.4.2-20140201 and having trouble finding the Supersu icon. It's looks hidden because it was still working, lucky I found this post :

Latest nightlies for Omni should integrate SuperSU into the settings. Scroll down in the system settings, the SuperSU config should be a little above the "About Phone" entry at the bottom. When it's integrated into system settings the icon in the app drawer is hidden.
Thanks
