So I'm having issues with altering my "Pages" icon within CandyBar. It won't show in the application folder for some reason. Not sure how I can fix this, but if anyone has any sort of a clue, let me know!
Basically, it looks like the very little customization you could do before in OS X will now be gone for good. Cannot replace icons on apps from App Store, cannot change Dock appearance, and as they write, soon cannot change icons for system apps, as well.
