Hello guys,I manually updated to CM12 (Non-rooted) and i found there are some things which need to be changed but couldnt find it in any themes! I also changes to "Blue ice" and "dark material" but there were no change in app drawer BG instead my contacts were vanished as ghost like text were not visible.

how do i change the background of app drawer since it is in "White" background,i want it in "transparent" or something "dark" like it was in CM11s.
same is for the contacts and keyboard as they are in white BG too.

Any Advice or Suggestion!
