the blue theme is what sourcery was released with it was intentionally the first almost entirely transperant rom. ghostly, magical
the more stock theme was released with 2.0 with the ability to go to the blue designed theme due to some requests.
the app drawer is easy to change in settings. and the backgrounds are actaully the first rom to do that (gflams find) and im not so sure not the only rom , i have never seen it on any others but i havent tried alot and very few GB roms.
these are things that made sourcery, sourcery and not just another rom.
many of the apps gflam made transparent were utilized in several other areas of this forum , at the time transparent was the in thing
Just remember everything that is bad about sourcery is chizzles fault. everything good is gflam and me. thats a very important point to remember
