Sometimes flashing custom kernel may break root, then you should reflash SuperSu, i did it and bbs works fine for me on Omni rom. Supersu zip you'll find here http://forum.xda-developers.com/showthread.php?t=1538053
Thanks @Doublemark, finally I have root for WSM, but Ican't install Mi-Tools.
Another problem is I can't set Nova as default launcher.
Anyway, @Wajk thanks a lot for your great job!
I haven't permission too, you need 10 post at least if you want write something ;)
I don't use the screencast/wifi display functions, so I can't tell you. The best feature of this ROM is OmniSwitch, for me of course ;)
I recommend this GApps http://forum.xda-developers.com/showthread.php?t=2240652.
Really small and there's everything you need, the rest you'll find in Google Play.
And everything work of course
I've had the same problem, but with "back button" only. After rebooting to MIUI system there's no problems with this. After last update of CM also no problem.

Make a folder Ringtones on SDCard and put your own ringtones in it. For notifications do the same, but in folder Notifications. It works on my phone.
