My concluison for now :
Not big improvement in ram consumption 741/842mb used is about average
No problems with conectivity wifi,3g...
Very clear sound in speaker and a bit louder
Camera working great and video record too
Exelent work of video player from s2
Transparent statusbar with shades looks great and have no bugs
Internet is ultra fast now compare to stock rom
Viber,skype,facebook,google+ works great no bugs
The only things bothers me is short batery life from 70% to 21% after 2hours heavy use wifi on apps instaling setings testing work on social apps etc
And litlle confusing thing default root app on rom is SUPERUSER and not SUPERSU (i have realy bad expirience with superuser)
CONCLUSION NO BUGS!!! FASTER THEN STOCK!!!NO BLOATWARE!!!NOT TOO MUCH EYE CANDY
) AND ULTRA STABLE FOR NOW
Two question for developer: is this realy android 4.4.2 ? And can you port fully working multiwindow on this rom?
